See what cosmic dust can do! Head outside this weekend for the peak of the Orionid meteor shower and an eyeful of zodiacal light.
You'd think scientists would have Saturn all figured out after watching it up close for 13 years. They don't.
Spacetime ripples from the neutron star smash-up usher in the age of multi-messenger astronomy.
The detection of a star-forming region 66,500 light-years from Earth, on the other side of our galaxy’s center, lends weight to the existence of an extended arm of the Milky Way.
New interpretations of oral accounts by Aboriginal Australians show that they included references to the variability of red giants Antares, Betelgeuse, and Aldebaran.
When the distant dwarf planet Haumea briefly slipped in front of a star last January, astronomers found more than they expected.
What's your pleasure when it comes to observing? Comets? Supernovae? Occultations? Get a sample of each and more in the upcoming week.
Roughly 3.5 billion years ago huge volcanoes released enough gas to cover the Moon with a thin atmosphere that was visible from Earth.
The close pass of near-Earth asteroid 2012 TC4 this week will give NASA a chance to test planetary-defense coordination.
What happens in the extreme environments of globular clusters when a star and a binary system meet? A team of scientists has new ideas about how these objects can deform, change their paths, spiral around each other, and merge.
Nicki Viall, a heliophysicist at Goddard Space Flight Center, shares her excitement over the Parker Solar Probe — the spacecraft that will allow scientists to "touch" the Sun.
Be sure to set the alarm so you don't miss the squeaky-tight conjunction of Venus and Mars Thursday morning. They'll stay close through the weekend.
The launch of Sputnik 1, Earth's first artificial satellite, paved the way for Moonwalking astronauts, robotic exploration of the planets, and space tourism.
Three American physicists have received the Nobel Prize in physics for their contributions to the discovery of gravitational waves.
Here’s an opportunity for amateurs to help improve our understanding of Neptune’s moon Triton.
The 2017 solar eclipse could easily be the most watched event in US history. Can we learn something from it?
The long-awaited James Webb Space Telescope — the successor to the Hubble Space Telescope — has slipped its launch date by several months. It will now launch between March and June 2019.
A few decades ago, astronomers thought they had figured out how quasars operate. Now, a new study has thrown a wrench in the works.
After protests and a judge's ruling brought the colossal Thirty Meter Telescope project to a halt, a state panel has cleared the way for its construction atop Mauna Kea to proceed.
Gas flows in the early universe may have kept clouds from collapsing too soon, enabling them to grow into massive black hole seeds.
Arecibo and its team rode out the largest storm in its history, but it's unclear what the moderate damage will mean for the radio observatory's future.
Teaming up with LIGO, Europe’s Virgo detector has bagged its first gravitational waves. The three-observatory detection enabled scientists to better pinpoint the merging black holes’ location.
The asteroid-bound Osiris-REX mission took time during last Friday's gravity assist maneuver to look back at its homeworld.
A new survey promises the most complete map of radio-emitting celestial sources ever made. It will reveal thousands of new objects after seven years of observation.
If you loved seeing August's solar eclipse and are eager to see another one, don't miss this live webinar on upcoming total and annular solar eclipses.
