The space rock that whacked Jupiter last month has lost its air of mystery.
Astronomers are rushing to study what appears to be the first known interstellar comet — and in some of the very earliest observations, it looks oddly familiar.
This weekend you can see live telescope views of an asteroid hurtling past Earth, thanks to astronomy broadcaster Slooh.
One of the most colorful wonders of the summer sky in the Northern Hemisphere, especially for deep-sky photographers, is the Rho Ophiuchi cloud complex.
The full moon of September 2019 also carries the title of the Harvest Moon for those living in the Northern Hemisphere.
Astronomers took the first multicolor images of a potentially interstellar comet, and it looks spectacular.
It's always nice to see old friends, and NASA's asteroid-monitoring team has a busy schedule this weekend (Sept. 13 and 14) doing just that.
At first, it was just another bright, fuzzy speck in the sky. But it may turn out to be something much more exciting: the second known object to hurtle through our solar system after leaving another.

The full "Harvest Moon" occurs Sept. 14, at 12:33 a.m. EDT (0433 GMT), a day after it reaches apogee, the farthest point from Earth in its orbit.
This week is a great time to see the solar system's outermost gas giant planet, if you have a telescope and a little patience.
It was only a matter of time: Amateur sleuths think they've tracked down the satellite that took a high-resolution image of the aftermath of an Iranian missile disaster.
If the sky is clear, you're in for a treat. The solar system's biggest planet — Jupiter — will nestle close to Earth's moon tonight (Sept. 5) for U.S. skywatchers.
In this week's evening sky, four small, faint constellations spread out near and within the Summer Triangle can be seen.
Here's a guide to SpaceX's launch schedule, other rocket missions, astronomical events of the next year, as well as milestones for spacecraft already in travel.
