- The Long-Lived Chicxulub Hydrothermal System Lasted 8 Million Yearsby Evan Gough (https://www.universetoday.com/authors/ion23drive) on June 23, 2026 at 10:20 pm
The asteroid that caused the extinction of the dinosaurs also created an underground environment suited to supporting new life, and new research suggests it lasted for millions of years longer than previously suspected. While previous research showed the buried hydrothermal system of porous rock, hot water, and chemical nutrients may have lasted 2 million years, new research says it lasted for 8 million years.
- Did Gravitational Tides Cause Earth's Extinctions?by Evan Gough (https://www.universetoday.com/authors/ion23drive) on June 23, 2026 at 7:24 pm
Many of Earth's mass extinctions await clear explanations. We know an impact wiped out the dinosaurs, but what about the planet's other extinction events? New research says flybys of planetary mass objects could've been responsible.
- Radio Observations Reveal the Secret of Early Galaxy Growthby Matthew Williams (https://www.universetoday.com/authors/houseofwilliams) on June 23, 2026 at 6:39 pm
Astronomers have discovered a huge reservoir of cold molecular gas, the direct fuel for star formation, in REBELS-25, a massive, star-forming galaxy.The team, led from Leiden University, focused on REBELS-25, seen when the universe was only about 700 million years old, around 5% of its current age. Astronomers use “redshift” to describe this distance, which measures how much the universe’s expansion has stretched a galaxy’s light to redder wavelengths.
- Ariane 6 Sets New Record for Europe with More Powerful Boostersby Matthew Williams (https://www.universetoday.com/authors/houseofwilliams) on June 23, 2026 at 5:49 pm
On 17 June at 09:21 local time (13:21 BST, 14:21 CEST) Ariane 6 flight VA269 soared to orbit from Europe’s Spaceport in French Guiana. 36 satellites for Amazon’s Leo constellation were placed into their orbit just over an hour after liftoff – the eighth successful mission insertion in a row for Europe’s newest rocket.
- This is the First Pair of Sibling Supernova Remnantsby Evan Gough (https://www.universetoday.com/authors/ion23drive) on June 23, 2026 at 5:18 pm
Astrophysicists have found what is likely the very first pair of sibling supernova remnants. One is the well-known Jellyfish Nebula, and the other was long thought to be hidden in the bright glare from the Jellyfish. The pair are connected by a bright filament of gas.
- The Solar Gravitational Lens Could Map White Dwarfs and Black Holesby Andy Tomaswick (https://www.universetoday.com/authors/andy-tomaswick) on June 23, 2026 at 1:11 pm
It feels like every few months we get to report on another academic paper coming out singing the praises of the Solar Gravitational SGL (SGL). Partly, this is due to Dr. Slava Turyshev’s astounding productivity in terms of pumping out academic articles, but partly because such a ground-breaking mission has lots of positive aspects, but also challenges that need to be addressed. A new paper, available in pre-print on arXiv from Dr. Turyshev, stresses an often overlooked feature of the SGL - how useful it can be at imaging things other than far away exoplanets.
