To celebrate Hubble's 28th birthday NASA is releasing a brand-new image of the Lagoon Nebula, a vast stellar nursery.
A mini-satellite demonstrates exoplanet-hunting technology, a superconducting camera tests its abilities to image exoplanets, and bad news for life on Proxima Centauri b.
Astronomy news this week: Hubble images the most distant star, radio telescopes combine forces to probe black hole jet, and neutron star hotspots explained.
A new study has uncovered a dozen stellar-mass black holes within 3 light-years of the supermassive black hole at our galaxy’s core — and these might be just the tip of the iceberg.
NASA officials announced Wednesday that the James Webb Space Telescope launch would be delayed until approximately May 2020. But before the mission can launch, its managers may have to face Congress.
Trappist-1's water-rich planets, a new measure of the solar system's planet-forming history, and an explanation for luminous, short-lived exploding stars.
New ALMA observations reveal a fiber-like structures within a longer, well-studied filament. These fibers contain the seeds of future stars.
Stephen Hawking, renowned physicist, famed science communicator, and all-around inspiration, has passed away at the age of 76.
A long-ago encounter between our galaxy and an orbiting dwarf might have ejected some of the Milky Way’s stars.
A non-partisan government office has issued a report warning of additional delays for the James Webb Space Telescope, which could pit the mission against its funding cap.
It turns out that neutron stars — not black holes — power at least some ultraluminous X-ray sources.
Astronomers have detected a torus rotating around the supermassive black hole at the center of spiral galaxy Messier 77, collecting observations that may shed light on why these weird structures exist.
Scientists have finally confirmed a decades-old theory on what causes the faint flickering seen in the Northern Lights toward dawn.
Two new studies of the seven planets orbiting TRAPPIST-1 shed light on how these worlds formed and what they look like now.
Dark matter particles may travel more slowly than we thought, hindering their detection. Dust storms may aid atmospheric loss on Mars. And a new mission is investigating magnetic fields at an unprecedented scale.
If you're not in the right place in the right time, you can still view Wednesday morning's total lunar eclipse online via several live streams. We list several options here.
Amateur astronomer Donald Bruns has received the Chambliss Amateur Achievement Award from the American Astronomical Society for his work in repeating and improving upon an iconic experiment during the August 2017 total solar eclipse.
Supermassive black holes are difficult to observe and measure, yet they have profound effects on their host galaxies. Read up on the latest black hole discoveries presented at the Washington D.C. meeting of the American Astronomical Society.
New observations of galaxies in a universe just 800 million years old show that they’ve already settled into rotating disks. They must have evolved quickly to display such surprising maturity.
Iron-rich stars host planets on closer orbits than their iron-poor siblings, astronomers find. The results could help reveal how planets form.
A new study found more massive stars than expected in an intensely star-forming region. The results beg the question whether the process of star formation really is universal.
Multiple gravitational-wave detections, a total solar eclipse, and exploration of the outer system number among the top astronomy news stories of the year.
Scientists have applied a brand of artificial intelligence to data from the exoplanet-hunting Kepler satellite, resulting in the discovery of the first eight-planet system outside our own.
New analysis from the New Horizons team suggest that the spacecraft's next target in the Kuiper Belt might have a third companion.
A combo of Hubble and Gaia data reveal the distribution of dark matter in a tiny galaxy by tracking the galaxy’s stars.
