Alien life Is Out There. But Our Theories Are Steering Us Away from It. | Live Science

If we discovered evidence of alien life, would we even realize it? Life on other planets could be so different from what we’re used to that we might not recognize any biological signatures that it produces. Recent years have seen changes to our theories about what counts as a biosignature and which planets might be habitable, and further turnarounds are […]

Aurora, Meet Airglow

“Aurora, Meet Airglow” Two of Earth’s most colorful upper atmospheric phenomena, aurora and airglow, met just before dawn in this photo shot by an astronaut on the International Space Station (ISS). Wavy green, red-topped wisps of aurora borealis appear to intersect the muted red-yellow band of airglow as the ISS passed just south of the Alaskan Peninsula. […]

Black hole the size of a grapefruit lurking at the edges of our solar system ‘could be Planet X’- Technology News, Firstpost

Scientists are now trying to figure out if a grapefruit-sized blackhole actually lurks at the fringes of our outer solar system. In the last few years, researchers have noticed an odd clustering of multiple trans-Neptunian objects (TNOs), which are found in the far outer solar system… MORE ABOUT THIS ARTICLE IN THE LINK BELOW… https://www.firstpost.com/tech/science/black-hole-the-size-of-a-grapefruit-could-be-planet-x-is-lurking-in-the-outer-edges-of-the-solar-system-8594001.html

Extraterrestrial Life Could Be Purple | Live Science

Alien life might be purple. That’s the conclusion of a new research paper that suggests that the first life on Earth might have had a lavender hue. In the International Journal of Astrobiology, microbiologist Shiladitya DasSarma of the University of Maryland School of Medicine and postdoctoral researcher Edward Schwieterman at the University of California, Riverside, argue that before […]

Mysterious ‘Planet Nine’ on the solar system’s edge may not be real

Things aren’t looking so good for Planet Nine. Astronomers have been seeking signs of a purported giant planet in the outer reaches of our solar system since 2014, but new observations hint that it may not actually be there…Read More about this in link… Read more: https://www.newscientist.com/article/2241222-mysterious-planet-nine-on-the-solar-systems-edge-may-not-be-real/#ixzz6KMA92xqU

Proxima Centauri, the sun’s nearest neighbor, may host a 2nd alien planet. Meet Proxima c.

The newly detected icy world remains a candidate planet for now. Proxima b may not be an only child after all. In August 2016, astronomers announced that a roughly Earth-size exoplanet circles the closest star to the sun, the red dwarf Proxima Centauri, which lies a mere 4.2 light-years from us. (For perspective, the Milky Way galaxy’s spiral disk […]
