The Eta Aquarids is one of the fastest meteor showers. Its specks pierce the sky at about 148,000 miles per hour.
There are times when I glance at an image and right away I know something is peculiar about it. Such was the case for UGC 477, the very lovely but decidedly weird galaxy pictured above. The image was taken using Hubble Space Telescope, and only shows two colors; usually these images are the more natural-looking three-color red/green/blue composites. Show More Summary
The solar system beyond Neptune is full of worlds hosting moons. Now we know that the dwarf planet Makemake has one of its very own.

A new study just published in the journal Nature Climate Change reached an interesting, if not totally surprising, conclusion: The Earth has become significantly greener over the past 33 years. The main reason? All the extra carbon dioxide...Show More Summary
This is just too cool. Click in the video and drag it around. Hint: At the beginning, tilt up. The Falcon 9 booster landing on April 8, 2016 was pretty amazing. It was windy out, as you can see from the video; once the booster made contact it slid a few meters. Show More Summary
Another day, another weird Facebook astronomy hoax. The photo with the caption above have been spread around Facebook quite a bit the past few days; it shows Saturn looming huge in the sky over a city, with the annotation, “On 5/1/16 Saturn will be the closest it ever has been to Earth.

HiRISE Principal Investigator Alfred McEwen explains an imaging technique known as Super-Resolution Restoration (SRR), and how it could come in handy for high-resolution imaging of the Red Planet.
The Universe is a bit bent. You’d think that light would travel in straight lines, going directly from point A to point B. But it’s more complicated than that. Space is curved, warped, distorted by the matter lodged within it. It’s hard...Show More Summary
SpaceX's announcement that it will send Dragon capsules to Mars demonstrates the advantage of having a clear plan to explore the red planet. NASA should take note.
Eugene Cernan's career was by any measure a triumph but a new profile spares a thought for the people left in his wake
Serbian artist Ivica Stoši? used Clementine and Kaguya data to give a glimpse of the phases of the lunar farside.
Two modern engineering marvels crossed paths this week here in Central America, as the last unflown space shuttle external fuel tank passed through the Panama Canal during a multi-week voyage from New Orleans to Los Angeles.
As our globe heats up, the effects of those rising temperatures are complex and varied. Overall, we call these effects “climate change”, but that’s an umbrella phrase that covers a vast number of changes. Melting polar ice, glacial melt,...Show More Summary
Russia’s space agency postponed the inaugural launch of a rocket from the Vostochny Cosmodrome in the Far East, citing technical problems.
Elon Musk’s company said it would dispatch its Dragon vessel to the planet, possibly as early as 2018, with a long-term goal of establishing colonies.
Well now, this is very cool: Astronomers have just announced that Makemake has a moon! Makemake (pronounced MAH-kay-mah-kay; it’s named after a Rapa Nui god who created humanity) is a Kuiper Belt object (or KBO), a large icy world orbiting the Sun way out past Neptune. Show More Summary
Astronomers found the moon, nicknamed MK2, in an image taken by the Hubble Space Telescope.
We all enjoy beautiful, multicolored sunsets. But what causes the brilliant oranges, pinks and purples that we see, and why does it change from day to day and season to season?
The Senate has released its draft of NASA's 2017 budget which, despite increasing NASA's top-line by $300 million, would cut $270 million from the Planetary Science Division. Here's why we shouldn't worry—yet.
