Thu, 03 Aug 2023 21:38:24 EDT //www.koonmotors.com/releases/2023/08/230803213824.htm To stick or to bounce: Size determines the stickiness of cosmic dust aggregates //www.koonmotors.com/releases/2023/07/230721113253.htm Current evidence suggests that microparticles of cosmic dust collide and stick together to form larger dust aggregates that may eventually combine and develop into planets. Numerical models that accurately characterize the conditions required for colliding microparticle aggregates to stick together, rather than bounce apart, are therefore paramount to understanding the evolution of planets. Recent modeling suggests that dust aggregates are less likely to stick together after a collision as the size of the aggregates increases.

Now researchers suggest looking at a new, unexpected and entirely unexplored place: The turbulent, energetic cocoons of debris that surround dying massive stars. Mon, 05 Jun 2023 18:12:02 EDT //www.koonmotors.com/releases/2023/06/230605181202.htm Eventually everything will evaporate, not only black holes //www.koonmotors.com/releases/2023/06/230602115051.htm New theoretical research has shown that Stephen Hawking was likely right about black holes, although not completely. Due to Hawking radiation, black holes will eventually evaporate, but the event horizon is not as crucial as had been believed. Gravity and the curvature of spacetime cause this radiation too. This means that all large objects in the universe, like the remnants of stars, will eventually evaporate. Fri, 02 Jun 2023 11:50:51 EDT //www.koonmotors.com/releases/2023/06/230602115051.htm Astrophysicists confirm the faintest galaxy ever seen in the early universe //www.koonmotors.com/releases/2023/06/230601155742.htm 大爆炸后,宇宙扩张和酷ed sufficiently for hydrogen atoms to form. In the absence of light from the first stars and galaxies, the universe entered a period known as the cosmic dark ages. The first stars and galaxies appeared several hundred million years later and began burning away the hydrogen fog left over from the Big Bang, rendering the universe transparent, like it is today. Researchers have now confirmed the existence of a distant, faint galaxy typical of those whose light burned through the hydrogen atoms; the finding should help them understand how the cosmic dark ages ended.

Wed, 31 May 2023 15:00:55 EDT //www.koonmotors.com/releases/2023/05/230531150055.htm X-ray emissions from black hole jets vary unexpectedly, challenging leading model of particle acceleration //www.koonmotors.com/releases/2023/05/230529171520.htm Black hole jets are known to emit x-rays, but how they accelerate particles to this high-energy state is still a mystery. Surprising new findings appear to rule out a leading theory, opening the door to reimagining how particle acceleration works. One model of how jets generate x-rays expects the jets' x-ray emissions to remain stable over long time scales. However, the new paper found that the x-ray emissions of a statistically significant number of jets varied over just a few years. Mon, 29 May 2023 17:15:20 EDT //www.koonmotors.com/releases/2023/05/230529171520.htm New study provides novel insights into the cosmic evolution of amino acids //www.koonmotors.com/releases/2023/05/230525141329.htm 艾尔l biological amino acids on Earth appear exclusively in their left-handed form, but the reason underlying this observation is elusive. Recently, scientists uncovered new clues about the cosmic origin of this asymmetry. Based on the optical properties of amino acids found on the Murchison meteorite, they conducted physics-based simulations, revealing that the precursors to the biological amino acids may have determined the amino acid chirality during the early phase of galactic evolution.

Tue, 02 May 2023 13:22:56 EDT //www.koonmotors.com/releases/2023/05/230502132256.htm Astronomers detect 'nearby' black hole devouring a star //www.koonmotors.com/releases/2023/04/230428130745.htm Astronomers have discovered a new 'tidal disruption event,' in which the center of a galaxy lights up as its supermassive black hole rips apart a passing star. The outburst is the closest tidal disruption event observed to date, and one of the first to be identified at infrared wavelengths. Fri, 28 Apr 2023 13:07:45 EDT //www.koonmotors.com/releases/2023/04/230428130745.htm Medium-sized black holes eat stars like messy toddlers //www.koonmotors.com/releases/2023/04/230425205336.htm In new 3D computer simulations, astrophysicists modeled black holes of varying masses and then hurled stars (about the size of our sun) past them to see what might happen. If they exist, intermediate-mass black holes likely devour wayward stars like a messy toddler -- taking a few bites and then flinging the remains across the galaxy. Tue, 25 Apr 2023 20:53:36 EDT //www.koonmotors.com/releases/2023/04/230425205336.htm Hubble sees possible runaway black hole creating a trail of stars //www.koonmotors.com/releases/2023/04/230406113958.htm There's an invisible monster on the loose, barreling through intergalactic space so fast that if it were in our solar system, it could travel from Earth to the Moon in 14 minutes. This supermassive black hole, weighing as much as 20 million Suns, has left behind a never-before-seen 200,000-light-year-long 'contrail' of newborn stars, twice the diameter of our Milky Way galaxy. It's likely the result of a rare, bizarre game of galactic billiards among three massive black holes.

Because of amino acids' relationship to living things scientists are eager to understand the origins of these molecules. After all, amino acids may have helped spawn life on Earth after being delivered here about 4 billion years ago by pieces of asteroids or comets.
