Astronomers used a cutting-edge camera mounted on one of the world’s largest telescopes to discover 83 new quasars – powered by central, supermassive black holes – in the very early universe.

Which stars are the most likely to have habitable planets? A new study suggest that K stars – between the dimmest M-type red dwarfs and sunlike stars – might provide the sweet spot for life.

University of Michigan astronomers say a hyper-runaway star didn’t originate from the galaxy’s center, as previously believed. Instead, they say, a cluster of young stars booted it from the galaxy’s disk.

Opportunity – nicknamed “Oppy” – was active on Mars from 2004 until June, 2018, when a planet-wide dust storm covered it. Its final image is a panorama, acquired from Opportunity’s final resting place in Mars’ Perseverance Valley.

They used the ALMA telescope to observe a slow outflow and a high speed jet from a newly forming star. These two streams appear misaligned and were apparently launched from different parts of the star-forming disk.

Scientists used the measured velocities of 44 globular star clusters to measure the mass of our home galaxy, the Milky Way.

There are at least 200 billion stars in our galaxy, and perhaps even a greater number of planets. Now a new study suggests there could be an additional 50 billion rogue planets, not orbiting any stars.

The red dwarf star TRAPPIST-1 – about 40 light-years away – has 7 Earth-sized exoplanets orbiting it. A new study puts limits on how many of those worlds have hazy or cloudy atmospheres.

It’s not supermassive, but only an intermediate-mass black hole, near the center of the Milky Way. It might be one of over 100 million quiet black holes lurking unseen in our galaxy.
