Astronomers have discovered auroras around a set of brown dwarfs — including one that wanders the galaxy by itself — indicating surprisingly strong magnetic fields in these failed stars.
The first "fast radio burst" detected by the Canadian CHIME radio telescope is a tantalizing hint of what’s to come.
The unique Parker Solar Probe launched on Sunday, August 12th, set to fly faster and come closer to the Sun than any spacecraft before it.
Faint echoes of light illuminate what really happened during the Great Eruption of the super-star Eta Carinae.
Sometimes, it's just as exciting to watch a celestial object fade or disappear as it is to see it explode. We celebrate the "return" of a mysterious variable star and prepare for Pluto to occult a star.
Plan for optimal conditions for the year’s Perseid meteor shower, early in the mornings of August 12th and 13th.
Astronomers have discovered a hiccup in stellar luminosities that may point to a new understanding of stellar structure.
New results show that the Medusae Fossae Formation, a set of broad and enigmatic plains, provides most of the fine dust found everywhere on the Martian surface.
As told in this month's astronomy podcast, August offers excellent viewing conditions for the always-flashy Perseid meteor shower — and a chance to see four bright planets at once.
An X-ray telescope recently installed on the International Space Station has provided a detailed look at a black hole feeding off its companion star.
Scientists studying microscopic minerals found in a meteorite have discovered evidence of the feistiness of the toddler Sun.
Astronomers have seen a star’s light redden as it passed our galaxy’s central black hole, just as general relativity predicts.
A radar instrument on one of the oldest operational Mars orbiters has discovered possible evidence of liquid water on Mars.
Not only will the Moon will be totally eclipsed this Friday, but Mars will be at opposition and shine in tandem with the red Moon all night!
HaloSat, a mini-satellite recently deployed from the International Space Station, is on the hunt for the universe's missing matter.
A new study says our neighbor galaxy’s big stellar halo and stellar evolution are due to a major collision that ended 2 billion years ago.
Wonder what to see now that Mars is at its biggest and brightest? Here are expert tips for when, where, and how to look.
A combination of neutrino detection and observations across the full spectrum of light has pinpointed a cosmic accelerator for the first time, revitalizing multi-messenger astronomy.
A new study explores the impacts of stars that age past the main sequence and evolve into red giants on the planets orbiting around them by looking at the orbits of gas giants closely circling evolved stars.
Catch up on this week in astronomy news with a trio of images: a pair of near-Earth asteroid twins, ground-based views that beat Hubble's, and the tumultuous galactic center.
Over the past 18 months, astronomers have painstakingly tracked a dozen tiny moons that they found circling the giant planet Jupiter.
Comet PanSTARRS (C/2017 S3) has erupted again! Now bright enough to see in binoculars, it might become a naked-eye object if it survives until perihelion.
On the night of July 27, 2018, the longest total lunar eclipse for the next 105 years will be visible across parts of Europe, Africa, Asia and Australia. Six months later, on January 20, 2019, there will be the 'Great American' lunar eclipse, where totality is visible across all 50 states.
A new National Academies study assesses NASA's efforts to protect neighboring worlds from contamination and recommends ways the space agency could do a better job.
There’s no hiding — changes in Earth’s atmosphere over the seasons are a dead giveaway to the fact that Earth hosts life. Now a new study explores whether we might use atmospheric seasonality like Earth’s to detect life on other planets. Looking for Change Most of the searches for life beyond our planet focus on…
