Astronomers' recent observations of our first-known interstellar visitor reveal that it is very strange indeed.
A new telescope called the SkyMapper has charted stars and galaxies across the southern sky, producing a map called "the best ever created."
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.
The International Astronomical Union has given its official approval for 86 star names, following up on last year's announcement of 227 official star names.
Here's a quick look at results announced at the 2017 American Geophysical Union meeting in New Orleans: exploding meteoroids, Saturn's ring-atmosphere connection, and more bright spots on Ceres.
New analysis from the New Horizons team suggest that the spacecraft's next target in the Kuiper Belt might have a third companion.
A slender Moon is an beautiful and inspiring sight. December and January offer several opportunities to see these exceptional crescents.
NASA’s Juno spacecraft peeked under the clouds of the most iconic weather feature in the solar system, Jupiter’s Great Red Spot, revealing a complex structure deep below the surface.
The habitability of distant exoplanets is dependent upon many factors — one of which is the activity of their host stars. To learn about which stars are most likely to flare, a recent study examines tens of thousands of stellar flares observed by Kepler. Need for a Broader Sample Most of our understanding of what…
Mark the date: December 13th. That's the night the Geminid meteor shower peaks. Highlighted by the return of its parent asteroid 3200 Phaethon, this year's show promises to be one of the best ever.
For a young woman who stared too long on August 21st, the partially eclipsed Sun left a lasting impression — on her retinas.
A combo of Hubble and Gaia data reveal the distribution of dark matter in a tiny galaxy by tracking the galaxy’s stars.
Astronomers have discovered a supermassive black hole scarfing down gas just 690 million years after the Big Bang.
NASA engineers directed the historic spacecraft Voyager 1 to fire its backup thrusters for the first time in 37 years.
A team of astronomers has found signs of small stars forming within a few light-years of the Milky Way’s central black hole.
A new analysis reveals that the gigantic impact that led to the Moon's formation might have also switched on Earth's magnetic field.
As you'll hear in December's astronomy podcast, early risers are treated with views of Jupiter (obvious), Mars (not as easy), and Mercury (timing is everything!).
Astronomers have obtained the most detailed radio image of hydrogen gas in a neighboring galaxy, revealing its structures with more precision than ever before.
The iconic image of faraway galaxies, and one of the most-observed regions of space, has just received a spectroscopic upgrade.
The parent asteroid of next month's Geminid meteor shower, 3200 Phaethon, is about to make a historically close flyby. Get ready to watch it race across the sky.
A hunt for merging dwarf galaxies has yielded an intriguing result: 180 million light-years away, a galaxy very similar to the Milky Way — with two dwarf-galaxy satellites just like our own Magellanic clouds
Previous studies of 55 Cancri e haven’t been able to determine whether this super-Earth hosts an atmosphere. A new study settles the question.
The U.S. National Science Foundation will continue to fund the iconic radio dish, though at a much-reduced level, as it seeks partners to share in the facility's operation.
The transition from sodium lights to LEDs, the so-called “lighting revolution”, was supposed to reduce energy consumption and bring back the starry sky, but new satellite data indicate it’s not working out that way.
With exoplanet Ross 128b in the news, we pay a visit to the star that sustains this potentially habitable exoplanet.
