Do You See the “Cosmic Bat” in NGC 1788?
|
|
2,000 light years away, in the Orion constellation, lurks an eerie looking creature, made of glowing gas lit up by young stars: the Cosmic Bat. Its real name is NGC 1788. It’s a reflection nebula, meaning the light of nearby stars is strong enough to light it up, but not strong enough to ionize the …

This Star has been Kicked Out of the Milky Way. It Knows What It Did.
|
|
Every once in a while, the Milky Way ejects a star. The evicted star is typically ejected from the chaotic area at the center of the galaxy, where our Super Massive Black Hole (SMBH) lives. But at least one of them was ejected from the comparatively calm galactic disk, a discovery that has astronomers rethinking …

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 …

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 …

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 …
