A study of a sample of galaxies that existed up to 12.5 billion years ago has provided further evidence that radiation from active supermassive black holes suppresses star formation.

Astronomers Find 116,000 New Variable Stars
What do two guys from Ohio, the GAIA mission, a worldwide network of ground-based telescopes, machine learning, and citizen scientists all have to do with each other? Thanks to this interesting combo of people and computers, astronomers now have more than 116,000 new variable stars to study. Until now, they knew of about 46,000 of these stars in the Milky Way Galaxy. They had observed maybe 10,000 or so in other galaxies. The discovery gives astronomers even more chances to study variables and understand why they behave the way they do.
Objects That Share the Same Orbit are Common in the Solar System. But we’ve Never Seen co-Orbital Exoplanets. Why?
“Where are all the Trojans” is a question valid in both the study of ancient history and the study of exoplanets. Trojan bodies, which share orbital paths with other, larger planets, are prevalent in our solar system – most obviously in the Trojan asteroids that follow Jupiter around on its orbital path. However, they seem absent from any star system found with exoplanets. Now, a team of researchers from the SETI Institute and NASA’s Ames Research Center thinks they have found a reason why.
Russian Soyuz rocket poised for launch with space station cargo freighter
NASA TV (English)
Roscosmos Webcast (Russian)
Russia’s Progress MS-20 cargo freighter is set for launch Friday on a fast-track, three-and-a-half hour rendezvous with the International Space Station to deliver around three tons of fuel, food, and supplies for the lab’s seven-person crew.
A Pulsar has Been Found Turning so Slowly Astronomers Didn't Even Think it was Possible: Once Every 76 Seconds
Astronomy is progressing rapidly these days, thanks in part to how advances in one area can contribute to progress in another. For instance, improved optics, instruments, and data processing methods have allowed astronomers to push the boundaries of optical and infrared to gravitational wave (GW) astronomy. Radio astronomy is also advancing considerably thanks to arrays like the MeerKAT radio telescope in South Africa, which will join with observatories in Australia in the near future to create the Square Kilometer Array (SKA).
The Stars in Other Galaxies are Generally Heavier Than the Milky Way’s Stars
How many of what kinds of stars live in other galaxies? It seems like a simple question, but it’s notoriously hard to pin down, because astronomers have such a difficult time estimating stellar populations in remote galaxies. Now a team of astronomers has completed a census of over 140,000 galaxies and found that distant galaxies tend to have heavier stars.
