Image Cache: I'm not usually one of those "check out this beautiful planet photo" people (jk, I am). But seriously, the images coming from the citizen scientists looking at Juno data are all incredible. I'm not sure how this latest one can even be real.

The National Weather Service says that the most likely explanation for an object which sent out illumination and a sonic boom throughout southwest Michigan, five other US states, and Canada on Tuesday night local time was the breakup of a meteor, WXYZ reported. The American Meteor Society collected at least 200 reports of the incident, which for around a second was so bright it lit parts of the Detroit region like it was daytime.
There may be at least half a million pieces of man-made junk orbiting this planet. Tiny pieces can travel around 10km/s, far faster than a bullet. The International Space Station has had to adjust its orbit just to avoid the stuff. People are rightfully concerned about what to do with all this orbital litter.
Contradictory accounts are emerging in the wake of the apparent failure of the Zuma mission - a secretive multibillion-dollar spy satellite that was launched by SpaceX from Cape Canaveral, Florida this past weekend. Everything seemed fine on the dayas the spy satellite was launched aboard a Falcon 9 rocket. SpaceX founder Elon Musk even tweeted about it, dropping a super-sweet photo of the launch.
Today, Elon Musk's SpaceX will launch "Zuma," a mysterious government spacecraft of unknown purpose, on one of its partially-reusable Falcon 9 two-stage rockets from Launch Complex 40 at Florida's Cape Canaveral Air Force Station. The exact time of the launch has yet to be set, though SpaceX has set a two-hour window beginning at 12 AEDT. That's lunchtime today.
Our Milky Way galaxy isn't alone in this corner of space -- it's orbited by a few smaller dwarf galaxies, including the Large Magellanic Cloud. Inside that cloud is 30 Doradus (or the Tarantula Nebula), a "starburst" where stars are formed at a much higher rate than the surrounding area. And 30 Doradus has too many massive stars.
Slow waves meander westward out in the deep ocean south of Australia. Sometimes they carry with them carry large eddies, whirlpools over 161km across. But every so often, these whirlpools combine into double whirlpools and travel across the ocean 10 times faster than the rest of the whirlpools, moving in sync for months and potentially transporting minerals and nutrients with them.
A total solar eclipse by itself isn't so unusual - the moon shades the Sun every 18 months, from the view of somewhere on Earth. But this year's "Great American Eclipse" was special simply for how much inhabited land it covered, crossing the length of America from Oregon to South Carolina. And that led to some amazing new scientific observations.
Astronomers spend their days looking at the sky. Maybe some crazy complex new telescope is helping, or some form of AI is teasing the complexities out of vast piles of data. It's still just the sky. The sky isn't immutable, though. Some of the most interesting science happens when brief blips pass into and out of existence. These dots send their light in the form of radio waves, microwaves, visible light and gamma rays into measuring apparatuses and tell us something new about the universe. They might even send space itself rippling with gravitational waves.
Mars looks like it used to have water - perhaps even entire oceans. But not today. Today, scientists can't even decide whether it's got slight trickles darkening the dirt on its mountainsides. If Mars did once have oceans, then where did they go?
August's landmark observation of two colliding neutron stars was incredible for its immediate impact on astronomy. It answered questions, like "where did the universe's gold come from" and "how fast is the universe expanding?" But it left behind mysteries, too. Like, "what the hell is going on with those gamma rays?"
