Astronomers discover 83 more supermassive black holes

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.

Storm in a cosmic teacup

Nicknamed the Teacup because of its shape, this quasar is causing a cosmic storm in a distant galaxy. The source of the squall is a supermassive black hole buried at a galaxy's center.

Mining the moon

How can the cost of space travel – to and from the moon and possibly to Mars - be reduced? One approach is to mine the moon for necessary resources.

Goldilocks stars: Just right for habitable planets

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.

Hyper-runaway star fled Milky Way disk

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.

See the Opportunity rover’s last image

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.

Woot! 4,001 exoplanets and counting 

The Exoplanet Team, led by the Observatoire de Paris, announced this week that the list of known exoplanets - planets orbiting distant stars - has grown to 4,001!

Small asteroid to sweep closer than moon’s distance

The house-sized asteroid - designated 2019 EA2 - will pass safely by our planet on the night of March 21-22, 2019.

Astronomers probe a baby star’s mystery gas flows

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.

How Hubble and Gaia weighed the Milky Way

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