Astronomers detect universe’s very first molecule in a dying star, the helium hydride ion HeH+
Key Takeaways The universe’s first molecule, helium hydride, was formed shortly after the Big Bang. NASA’s SOFIA telescope recently detected helium hydride in the planetary […]
This Black Hole Consumes Material at Over 40 Times The Theoretical Limit
Key Takeaways: A supermassive black hole in galaxy LID-568 is consuming material 40 times faster than its theoretical limit. This rate is beyond the Eddington […]
What if the universe had no beginning?
Key Takeaways: A new quantum gravity theory, causal set theory, suggests space-time is made up of “atoms.” This theory could imply that the universe had […]
Astronomers observed 3,000 light-years “light echo” from this dying supermassive black hole
Key Takeaways: Supermassive black holes, like the one in galaxy Arp 187, can host active galactic nuclei (AGN) that emit powerful radiation and jets of […]
Alien civilizations are more likely to be artificial than biological, scientists say
Key Takeaways: Advanced alien life, if found, is likely to be artificial rather than organic. Extraterrestrial civilizations may evolve beyond biological forms, moving toward artificial […]
A swarm of black holes has been detected moving through the Milky Way
Key Takeaways: Palomar 5, a star cluster with a long stellar stream, likely hosts over 100 stellar-mass black holes. Black holes in the cluster’s core […]
Scientists announce a breakthrough in determining life’s origin on Earth—and maybe Mars
Key Takeaways: RNA molecules can form spontaneously on basalt lava glass, which was abundant on early Earth. The study suggests that early impacts and volcanic […]
“Extraordinary” phenomenon as a white dwarf star flickers “on and off” every 30 minutes
Key Takeaways: A white dwarf star in the TW Pictoris system switches “on and off” every 30 minutes. This rapid dimming is caused by unusual […]
Astronomers have discovered the largest radio galaxy ever, 100 times larger than the Milky Way
Key Takeaways: Alcyoneus, a colossal radio galaxy, spans at least 16 million light-years across space. Discovered by accident, the galaxy lies about 3 billion light-years […]
