Earth’s magnetic field creates a bow shock in front of itself (pale blue area) traveling through solar wind (orange area)/NASA,Goddard Space Flight Center

One reason why life can exist here. From ScienceDaily:

A new study describes the first observations of the process of electron heating in Earth’s bow shock. The researchers found that when the electrons in the solar wind encounter the bow shock, they momentarily accelerate to such a high speed that the electron stream becomes unstable and breaks down. This breakdown process robs the electrons of their high speed and converts the energy to heat.

The results add an important new dimension to scientists’ understanding of Earth’s magnetic field and its ability to protect the planet from harmful particles and radiation. The research paper was published in the journal Physical Review Letters on May 31, 2018.

“If you were to stand on a mountaintop, you might get knocked over by a fast wind,” explained Li-Jen Chen, lead author of the study and an associate research scientist in the UMD Department of Astronomy. “Fortunately, as the solar wind crashes into Earth’s magnetic field, the bow shock protects us by slowing down this wind and changing it to a nice, warm breeze. We now have a better idea how this happens.” Paper. (paywall) – L.-J. Chen, S. Wang, L. B. Wilson, S. Schwartz, N. Bessho, T. Moore, D. Gershman, B. Giles, D. Malaspina, F. D. Wilder, R. E. Ergun, M.

Accounting for how life continues to exist is unfairly underrated compared with trying to explain how it got started.

See also: Skeptic: Panspermia (life came from elsewhere than Earth) is “pseudoscience” One gets the impression that the journal Progress in Biophysics and Molecular Biology, which published Steele et al.’s paper, will be reluctant to start a lively discussion about origin of life again. Nothing to see here, folks. Move along.

Of related note: Many more parameters than just the magnetic field are required to be met in order for life to be possible on Earth:
Linked from Appendix C from Dr. Ross's book, 'Why the Universe Is the Way It Is'; Probability Estimates for the Features Required by Various Life Forms: Excerpt: Requirements to sustain bacteria for 90 days or less: Probability for occurrence of all 501 parameters approx. 10-614 dependency factors estimate approx. 10^-303 longevity requirements estimate approx. 10^22 Probability for occurrence of all 501 parameters approx. 10^-333 Maximum possible number of life support bodies in observable universe approx. 10^22 Thus, less than 1 chance in 10^311 exists that even one such life-support body would occur anywhere in the universe without invoking divine miracles. Requirements to sustain unicellar life for three billion year: Probability for occurrence of all 676 parameters approx. 10^-859 dependency factors estimate approx. 10^-303 longevity requirements estimate approx. 10^22 Probability for occurrence of all 676 parameters approx. 10^-578 Maximum possible number of life support bodies in observable universe approx. 10^22 Thus, less than 1 chance in 10^556 exists that even one such life-support body would occur anywhere in the universe without invoking divine miracle Requirements to sustain intelligent physical life: Probability for occurrence of all 816 parameters approx. 10^-1333 dependency factors estimate approx. 10^-324 longevity requirements estimate approx. 10^45 Probability for occurrence of all 816 parameters approx. 10^-1054 Maximum possible number of life support bodies in observable universe approx. 10^22 Thus, less than 1 chance in 10^1032 exists that even one such life-support body would occur anywhere in the universe without invoking divine miracle http://d4bge0zxg5qba.cloudfront.net/files/compendium/compendium_Part3_ver2.pdf Science Increasingly Makes the Case for God The odds of life existing on another planet grow ever longer. Intelligent design, anyone? - By ERIC METAXAS - Dec. 24, 2014 Excerpt: Today there are more than 200 known parameters necessary for a planet to support life —every single one of which must be perfectly met, or the whole thing falls apart. Without a massive planet like Jupiter nearby, whose gravity will draw away asteroids, a thousand times as many would hit Earth’s surface. The odds against life in the universe are simply astonishing. Yet here we are, not only existing, but talking about existing. What can account for it? Can every one of those many parameters have been perfect by accident? At what point is it fair to admit that science suggests that we cannot be the result of random forces? Doesn’t assuming that an intelligence created these perfect conditions require far less faith than believing that a life-sustaining Earth just happened to beat the inconceivable odds to come into being? http://inters.org/files/metaxas-science-increasingly.pdf Eric Metaxas - Does Science Argue for or against God? – (2015) video https://www.youtube.com/watch?v=UjGPHF5A6Po
Such a multitude of life permitting parameters caused Eric Metaxas to remark, "our existence is an outrageous and astonishing miracle, one so startlingly and perhaps so disturbingly miraculous that it makes any miracle like the parting of the Red Sea pale in such insignificance that it almost becomes unworthy of our consideration, as though it were something done easily by a child, half-asleep."
“Reason and science compels us to see what previous generations could not: that our existence is an outrageous and astonishing miracle, one so startlingly and perhaps so disturbingly miraculous that it makes any miracle like the parting of the Red Sea pale in such insignificance that it almost becomes unworthy of our consideration, as though it were something done easily by a child, half-asleep. It is something to which the most truly human response is some combination of terror and wonder, of ancient awe, and childhood joy.” Eric Metaxas – Miracles – pages 55-56
Moreover, many people falsely believe that, due to the Copernican Revolution, that the earth no longer has a special position within the universe. But that belief is no longer true. Both of our best theories in science, i.e. General Relativity and Quantum Mechanics, as well as 'strange anomalies' in the Cosmic Background Radiation that mysteriously line up with the Earth, have now overturned what is known as the Copernican Principle and/or the Principle of Mediocrity: Einstein himself stated, The two sentences: “the sun is at rest and the earth moves” or “the sun moves and the earth is at rest” would simply mean two different conventions concerning two different CS [coordinate systems].”
“Can we formulate physical laws so that they are valid for all CS [coordinate systems], not only those moving uniformly, but also those moving quite arbitrarily, relative to each other? […] The struggle, so violent in the early days of science, between the views of Ptolemy and Copernicus would then be quite meaningless. Either CS could be used with equal justification. The two sentences: “the sun is at rest and the earth moves” or “the sun moves and the earth is at rest” would simply mean two different conventions concerning two different CS.” Einstein, A. and Infeld, L. (1938) The Evolution of Physics, p.212 (p.248 in original 1938 ed.);
Even Stephen Hawking himself, who once claimed that we are just chemical scum on an insignificant planet, stated that it is not true that Copernicus proved Ptolemy wrong,,, the real advantage of the Copernican system is simply that the equations of motion are much simpler in the frame of reference in which the sun is at rest.”
“So which is real, the Ptolemaic or Copernican system? Although it is not uncommon for people to say that Copernicus proved Ptolemy wrong, that is not true. As in the case of our normal view versus that of the goldfish, one can use either picture as a model of the universe, for our observations of the heavens can be explained by assuming either the earth or the sun to be at rest. Despite its role in philosophical debates over the nature of our universe, the real advantage of the Copernican system is simply that the equations of motion are much simpler in the frame of reference in which the sun is at rest.” Stephen Hawking – The Grand Design – pages 39 – 2010
Even individual people, as the following article makes clear, can be considered to be central in the universe according to the four-dimensional space-time of General Relativity,,,
You Technically Are the Center of the Universe – May 2016 Excerpt: (due to the 1 in 10^120 finely tuned expansion of the 4-D space-time of General Relativity) no matter where you stand, it will appear that everything in the universe is expanding around you. So the center of the universe is technically — everywhere. The moment you pick a frame of reference, that point becomes the center of the universe. Here's another way to think about it: The sphere of space we can see around us is the visible universe. We're looking at the light from stars that's traveled millions or billions of years to reach us. When we reach the 13.8 billion-light-year point, we're seeing the universe just moments after the Big Bang happened. But someone standing on another planet, a few light-years to the right, would see a different sphere of the universe. It's sort of like lighting a match in the middle of a dark room: Your observable universe is the sphere of the room that the light illuminates. But someone standing in a different spot in the room will be able to see a different sphere. So technically, we are all standing at the center of our own observable universes. https://mic.com/articles/144214/you-technically-are-the-center-of-the-universe-thanks-to-a-wacky-physics-quirk
Whereas, on the other hand, in Quantum Mechanics it is the measurement itself that gives each observer a privileged frame of reference in the universe. As the following article states, "It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it,",,,
Experiment confirms quantum theory weirdness - May 27, 2015 Excerpt: Common sense says the object is either wave-like or particle-like, independent of how we measure it. But quantum physics predicts that whether you observe wave like behavior (interference) or particle behavior (no interference) depends only on how it is actually measured at the end of its journey. This is exactly what the ANU team found. "It proves that measurement is everything. At the quantum level, reality does not exist if you are not looking at it," said Associate Professor Andrew Truscott from the ANU Research School of Physics and Engineering. http://phys.org/news/2015-05-quantum-theory-weirdness.html
Richard Conn Henry, who is Professor of Physics at John Hopkins University, states “It is more than 80 years since the discovery of quantum mechanics gave us the most fundamental insight ever into our nature: the overturning of the Copernican Revolution, and the restoration of us human beings to centrality in the Universe.”
"It is more than 80 years since the discovery of quantum mechanics gave us the most fundamental insight ever into our nature: the overturning of the Copernican Revolution, and the restoration of us human beings to centrality in the Universe. And yet, have you ever before read a sentence having meaning similar to that of my preceding sentence? Likely you have not, and the reason you have not is, in my opinion, that physicists are in a state of denial, and have fears and agonies that are very similar to the fears and agonies that Copernicus and Galileo went through with their perturbations of society." Richard Conn Henry - Professor of Physics - John Hopkins University
Moreover, there are Anomalies in the Cosmic Microwave Background Radiation that strangely line up with the solar system and earth.
Why is the solar system cosmically aligned? BY Dragan Huterer - 2007 The solar system seems to line up with the largest cosmic features. Is this mere coincidence or a signpost to deeper insights? Caption under figure on page 43: ODD ALIGNMENTS hide within the multipoles of the cosmic microwave background. In this combination of the quadrupole and octopole, a plane bisects the sphere between the largest warm and cool lobes. The ecliptic — the plane of Earth’s orbit projected onto the celestial sphere — is aligned parallel to the plane between the lobes. http://www-personal.umich.edu/~huterer/PRESS/CMB_Huterer.pdf
Moreover besides the earth and solar system lining up with the anomalies in the Cosmic Background Radiation, Radio Astronomy now reveals a surprising rotational coincidence for Earth in relation to the quasar and radio galaxy distributions in the universe:
Is there a violation of the Copernican principle in radio sky? - Ashok K. Singal - May 17, 2013 Abstract: Cosmic Microwave Background Radiation (CMBR) observations from the WMAP satellite have shown some unexpected anisotropies (directionally dependent observations), which surprisingly seem to be aligned with the ecliptic\cite {20,16,15}. The latest data from the Planck satellite have confirmed the presence of these anisotropies\cite {17}. Here we report even larger anisotropies in the sky distributions of powerful extended quasars and some other sub-classes of radio galaxies in the 3CRR catalogue, one of the oldest and most intensively studies sample of strong radio sources\cite{21,22,3}. The anisotropies lie about a plane passing through the two equinoxes and the north celestial pole (NCP). We can rule out at a 99.995% confidence level the hypothesis that these asymmetries are merely due to statistical fluctuations. Further, even the distribution of observed radio sizes of quasars and radio galaxies show large systematic differences between these two sky regions. The redshift distribution appear to be very similar in both regions of sky for all sources, which rules out any local effects to be the cause of these anomalies. Two pertinent questions then arise. First, why should there be such large anisotropies present in the sky distribution of some of the most distant discrete sources implying inhomogeneities in the universe at very large scales (covering a fraction of the universe)? What is intriguing even further is why such anisotropies should lie about a great circle decided purely by the orientation of earth's rotation axis and/or the axis of its revolution around the sun? It looks as if these axes have a preferential placement in the larger scheme of things, implying an apparent breakdown of the Copernican principle or its more generalization, cosmological principle, upon which all modern cosmological theories are based upon. http://arxiv.org/abs/1305.4134
Thus, contrary to popular belief, humans, and the earth beneath their feet, are not nearly as insignificant in this universe as many people, including many Christians, have been falsely led to believe by the Copernican principle Of related interest: Neil Turok states "We live in the middle between the largest scale in physics,,, and the tiniest scale [in physics].”

Now where are we? Well the size of a living cell is about 10 to the minus 5. Which is halfway between the two. In mathematical terms, we say it is the geometric mean.

The Earth as You've Never Seen it Before: Atmosphere, Airglow and Aurora - video https://vimeo.com/42909676 An average apple is about 225 millimeters around, and its skin is about 3 millimeters thick. If we compare the Earth and its atmosphere to an apple and its skin, the skin of the apple is about 20 times thicker relative to the size of the apple than the atmosphere is to the size of the Earth. The Cold Trap: How It Works - Michael Denton - May 10, 2014 Excerpt: As water vapor ascends in the atmosphere, it cools and condenses out, forming clouds and rain and snow and falling back to the Earth. This process becomes very intense at the so-called tropopause (17-10 km above sea level) where air temperatures reach -80°C and all remaining water in the atmosphere is frozen out. The air in the layer of the atmosphere above the troposphere in the stratosphere (extending up to 50 km above mean sea level) is absolutely dry, containing oxygen, nitrogen, some CO and the other atmospheric gases, but virtually no H2O molecules.,,, ,,,above 80-100 km, atoms and molecules are subject to intense ionizing radiation. If water ascended to this level it would be photo-dissociated into hydrogen and oxygen and, the hydrogen being very light, lost into space. Over a relatively short geological period all the water and oceans would be evaporated and the world uninhabitable.,,, Oxygen, having a boiling point of -183°C, has no such problems ascending through the tropopause cold trap into the stratosphere. As it does, it becomes subject to more and more intense ionizing radiation. However this leads,, to the formation of ozone (O3). This forms a protective layer in the atmosphere above the tropopause, perfectly placed just above the cold trap and preventing any ionizing radiation in the far UV region from reaching the H2O molecules at the tropopause and in the troposphere below. http://www.evolutionnews.org/2014/05/the_cold_trap_h085441.html Magnetic Fields: On Other Planets - April 2014 https://jolyastronomy.com/2014/04/19/magnetic-fields-on-other-planets/ image -Comparing Venus’, Earth’s, and Mars’ magnetic interactions with Solar Flares https://i2.wp.com/i.space.com/images/i/000/033/427/i02/venus-earth-mars-interacting-solar-wind.jpg Cosmic Rays Hit Space Age High Excerpt: "The entire solar system from Mercury to Pluto and beyond is surrounded by a bubble of solar magnetism called "the heliosphere." http://www.sciencedaily.com/releases/2009/09/090929133244.htmbornagain77

Of related note: How 'Space Shield' Protects Earth from "Sledgehammer Blow" of "Killer Electrons" - March 3, 2015 Excerpt: "On Oct. 8, 2013, an explosion on the sun's surface sent a supersonic blast wave of solar wind out into space. This shockwave tore past Mercury and Venus, blitzing by the moon before streaming toward Earth. The shockwave struck a massive blow to the Earth's magnetic field, setting off a magnetized sound pulse around the planet." Some of the data is analyzed at MIT's Haystack Observatory, where John Foster acts as associate director. He was surprised at how quickly the particles were accelerated by a factor of 10 in just 60 seconds. "Foster and his colleagues analyzed the probes' data, and laid out the following sequence of events: As the solar shockwave made impact, according to Foster, it struck "a sledgehammer blow" to the protective barrier of the Earth's magnetic field. But instead of breaking through this barrier, the shockwave effectively bounced away, generating a wave in the opposite direction, in the form of a magnetosonic pulse -- a powerful, magnetized sound wave that propagated to the far side of the Earth within a matter of minutes." This was "the first time the effects of a solar shockwave on Earth's radiation belts have been observed in detail from beginning to end." http://www.evolutionnews.org/2015/03/how_space_shiel094051.html Plasma plumes help shield Earth from damaging solar storms - March 6, 2014 Excerpt: Now scientists at MIT and NASA have identified a process in Earth's magnetosphere that reinforces its shielding effect, keeping incoming solar energy at bay. By combining observations from the ground and in space, the team observed a plume of low-energy plasma particles that essentially hitches a ride along magnetic field lines -- streaming from Earth's lower atmosphere up to the point, tens of thousands of kilometers above the surface, where the planet's magnetic field connects with that of the sun. In this region, which the scientists call the "merging point," the presence of cold, dense plasma slows magnetic reconnection, blunting the sun's effects on Earth. "The Earth's magnetic field protects life on the surface from the full impact of these solar outbursts," says John Foster, associate director of MIT's Haystack Observatory. "Reconnection strips away some of our magnetic shield and lets energy leak in, giving us large, violent storms. These plasmas get pulled into space and slow down the reconnection process, so the impact of the sun on the Earth is less violent." http://www.sciencedaily.com/releases/2014/03/140306142757.htm Scientists 'Iron Out' Phenomenon That Sustains Magnetic Field Of Earth - 2 June 2016 Excerpt: "Without Earth's magnetic field, life on the planet might not exist. For 3.4 billion years, this magnetic field has prevented Earth from becoming extremely vulnerable to high-energy particles called cosmic radiation. Scientists know that what generates the protective magnetic field is the low heat conduction of liquid iron in the planet's outer core. This phenomenon is known as "geodynamo." However, although geodynamo has been identified, experts have yet to understand how it was first created and sustained all throughout history....In the end, researchers found that the ability of iron to transmit heat were not at par with previous estimates of thermal conductivity in the core. It was actually between 18 and 44 watts per meter per kelvin. This suggests that the energy needed to sustain the geodynamo has been present since very early in Earth's history, researchers concluded. http://www.techtimes.com/articles/162458/20160602/scientists-iron-out-phenomenon-that-sustains-magnetic-field-of-earth.htm Here is a glimpse at how the aurora borealis is actually formed by solar flares interacting with the magnetic field: NASA Magnetic Reconnection - video http://www.youtube.com/watch?v=7_Gny2JVqQ8 The science behind northern lights - October 2, 2012 Excerpt: ,,,(solar) flares release a burst of charged particles, or plasma, into the solar system. When they come our way, they whack into the Earth's magnetosphere, which is made up of its own stream of charged particles. That collision causes particles to break free of the magnetosphere and cascade toward the Earth's magnetic field lines, usually traveling toward the poles. "The aurorae happen when these high-energy particles bap into atoms and molecules in the Earth's atmosphere, typically oxygen," Nemiroff said. Light is emitted as part of the reaction. Those particles can also wreak havoc. "The plasma cloud can cause the Earth's magnetic field to fluctuate," Nemiroff said. "At worst, that can knock out satellites and even power grids.",,, http://phys.org/news/2012-10-science-northern.htmlbornagain77
