New Ring of Dust Discovered in the Inner Solar System Discovering new things in space is a regular occurrence. Astronomers keep finding more distant objects in the outer reaches of the Solar System. Worlds like ‘The Goblin,’ ‘FarOut,’ and ‘FarFarOut‘ are stretching the limits of what our Solar System actually is. But finding new things in the inner Solar System is rare. “It’s not every … Continue reading “New Ring of Dust Discovered in the Inner Solar System” The post New Ring of Dust Discovered in the Inner Solar System appeared first on Universe Today.

This is the Final Photograph from Opportunity Sad. But beautiful. NASA has shared Opportunity’s final photograph from the surface of Mars. The rover’s final resting place is in Endeavour Crater, and barring any statistically unlikely event, it will sit there for centuries, millennia, or even longer. And instead of a tombstone, we have this final image. The image is a panorama, captured … Continue reading “This is the Final Photograph from Opportunity” The post This is the Final Photograph from Opportunity appeared first on Universe Today.

This is What It’ll Look Like When the Milky Way and Andromeda Galaxies Collide Billions of Years from Now What happens when two galaxies collide? The Milky Way and the Andromeda Galaxy are on a collision course, and in about 4.5 billion years, they will meet. Now astronomers using the Hubble have provided some visual insight into what that collision might look like. When two galaxies collide, it’s highly unlikely that any stars will … Continue reading “This is What It’ll Look Like When the Milky Way and Andromeda Galaxies Collide Billions of Years from Now” The post This is What It’ll Look Like WhenRead More →

China’s Lunar Rover Wakes Up and Gets to Work for its 3rd Lunar Day The China National Space Administration (CNSA) has released some new photos and updated the world on their lunar rover mission. The Yutu-2 rover is working its way into the history books on the lunar far side, exploring the Von Karman crater. It’s third lunar day is now in the record books.

Jupiter or Earth? Which One’s Which, and Why Do They Look so Similar? Jupiter: a massive, lifeless gas giant out there on the other side of the asteroid belt. It’s a behemoth, containing 2.5 times as much mass as all the other planets combined. To top it off, it’s named after the Roman God of War. Earth: a tiny rocky world, almost too close to the Sun, where … Continue reading “Jupiter or Earth? Which One’s Which, and Why Do They Look so Similar?” The post Jupiter or Earth?

A Newer, More Accurate Measurement Sets the Mass of the Milky Way at 1.5 Trillion Solar Masses Astronomers keep trying to measure the mass of the Milky Way and they keep coming up with different numbers. But it’s not that they’re bad at math. Measuring the mass of something as enormous as the Milky Way is confounding. Plus, we’re embedded in it; it takes some very clever maneuvering to constrain its mass. … Continue reading “A Newer, More Accurate Measurement Sets the Mass of the Milky Way at 1.5 Trillion Solar Masses” The post A Newer, More Accurate Measurement Sets the Mass of the MilkyRead More →

Massive Photons Could Explain Dark Matter, But Don’t I’ll be the first to admit that we don’t understand dark matter. We do know for sure that something funny is going on at large scales in the universe (“large” here meaning at least as big as galaxies). In short, the numbers just aren’t adding up. For example, when we look at a galaxy and … Continue reading “Massive Photons Could Explain Dark Matter, But Don’t” The post Massive Photons Could Explain Dark Matter, But Don’t appeared first on Universe Today.

It Took 10 Years to Confirm the First Planet Ever Found by Kepler Even though astronomy people are fond of touting the number of exoplanets found by the Kepler spacecraft, those planets aren’t actually confirmed. They’re more correctly called candidate exoplanets, because the signals that show something’s out there, orbiting a distant star, can be caused by something other than exoplanets. It can actually take a long time … Continue reading “It Took 10 Years to Confirm the First Planet Ever Found by Kepler” The post It Took 10 Years to Confirm the First Planet Ever Found by Kepler appeared first on Universe Today.

This is an Actual Photograph of the Shock Waves from Supersonic Jets Interacting with Each Other After more than 10 years of hard work, NASA has reached another milestone. We’re accustomed to NASA reaching milestones, but this one’s a little different. This one’s all about a type of photography that captures images of the flow of fluids. It’s called Schlieren Photography, and schlieren is German for “streaks.” It was first developed … Continue reading “This is an Actual Photograph of the Shock Waves from Supersonic Jets Interacting with Each Other” The post This is an Actual Photograph of the Shock Waves from Supersonic Jets InteractingRead More →

You’re in This Picture. It’s a Selfie Taken by SpaceIL’s Beresheet Lunar Lander on its Way to the Moon Israel’s space program doesn’t get a lot of headlines. Israel itself is in the news a lot, but usually for other reasons. But they do have a space program, and right now they have a lander, called Beresheet, on the way to the Moon.
