Hot Jupiter Endures Star-Powered Barbecue

You’re the grillmaster at the annual family 4th of July BBQ and you’re sweating bullets standing over the grill in the sweltering summer heat. You’re trying to stay cool by pressing a cold beer can on your forehead, but to no avail. You can’t go inside because, once again, you’re the grillmaster and need to watch the food simmering on your freshly cleaned grill. Your brother-in-law is a university astronomy professor and walks over asking how you’re doing. You say, “This heat is killing me. I feel hotter than the barbeque!” Your science teacher brother-in-law slyly says, “Try being an exoplanet.” You roll your eyes. from Universe Today https://ift.tt/srXnazI via IFTTT

The Long-Lived Chicxulub Hydrothermal System Lasted 8 Million Years

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. from Universe Today https://ift.tt/7dGCuSb via IFTTT

Did Gravitational Tides Cause Earth's Extinctions?

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. from Universe Today https://ift.tt/0e47EjU via IFTTT

Radio Observations Reveal the Secret of Early Galaxy Growth

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. from Universe Today https://ift.tt/NA7h9Dj via IFTTT

The Solar Gravitational Lens Could Map White Dwarfs and Black Holes

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. from Universe Today https://ift.tt/oT3YjiU via IFTTT

Happy Asteroid Day! Prize-Winning Plan Focuses on Space Infrastructure

A proposal to create a new network for monitoring cosmic threats to off-world infrastructure has won this year's Schweickart Prize, which recognizes bright ideas for planetary defense. from Universe Today https://ift.tt/s0n8uHQ via IFTTT

A Quasar at Cosmic Dawn Flickers into View

Astronomers have detected a flickering quasar called J0439+1634 as it appeared only 850 million years after the Big Bang. That discovery raises fresh questions about black hole formation and activity in the early Universe. The flickering light of this distant cosmic lighthouse showed that black hole at the heart of the quasr has a flat, pancake-shaped accretion disk. That shape is more familiar in modern-day quasars, which leads astronomers to wonder how these objects formed so quickly in the infant cosmos? from Universe Today https://ift.tt/4hqInrS via IFTTT
