The waxing Moon steps along nightly this week, from low in the western twilight with Venus and Spica over to Antares and then the Sagittarius Teapot. Meanwhile, the recurrent nova T Corona Borealis is keeping us waiting.
The BepiColombo mission has completed its fourth and closest pass yet of Mercury, giving us brand-new views of the planet's south pole region.
Astronomers may have finally solved the mystery of how dark space really is.
Billions of years ago, the close pass of another star might have sculpted the outer regions of our solar system.
A penumbral lunar eclipse is coming on September 17th, and that little shadow is something to look forward to.
A supermassive black hole has twice now grabbed gas from a passing star — and astronomers predict a third chance will come in early 2025.
Let’s go on a night-sky tour of the stars and planets that you’ll see overhead during August. Find a good seat for some great “shooting stars,” watch Saturn climb in the eastern sky in early evening, check out the summer's brightest stars, and start looking for a once-in-your-lifetime star blast.
Low in twilight, climbing Venus and descending Spica prepare to pass each other. After dark Vega crosses the zenith, and Scorpius beds down. Mercury shines at dawn.
Last month, astronomers discovered a giant black hole in Omega Centauri. But it might contain a swarm of stellar-mass black holes instead.
Did you know you can see the International Space Station even when it's in Earth's shadow? We explore possible reasons why.
New data from an array of telescopes has enabled astronomers to visualize the surface of the North Star, Polaris.
The worldwide network of radio dishes has achieved the highest resolution ever obtained from Earth’s surface.
Amateur astronomers have shown that the first satellites of the Chinese Qianfan (“Thousand Sails”) constellation are bright enough to be seen naked-eye.
New James Webb Space Telescope observations may have done with one of the longest-standing tensions in cosmology.
We're in peak Milky Way season, and the evenings have become dark and moonless. Andromegasus is up. So is Saturn. Before dawn, the late-risen Moon passes over Jupiter and Mars.
The European mission to Jupiter's icy moons provided us with some amazing views closer to home, of Earth and the Moon.
A Westfield, Massachusetts, teenager is the recipient of an award in recognition of her multi-faceted outreach activities.
New analysis reveals evidence of a super-Earth-mass exoplanet forming in the disk surrounding the star TW Hydrae.
This far-southern constellation contains some delightful sights for small telescopes.
Vega shines overhead as the zenith star at dusk. Jupiter and Mars are separating. When the Moon is just past full it poses next to Saturn — which, by no coincidence, is less than a month from opposition.
