…while light cannot escape a black hole, its extreme gravity warps space around it, which allows light to “echo,” bending around the back of the object. Thanks to this strange phenomenon, astronomers have, for the first time, observed the light from behind a black hole.

Einstein has been proven right. Again.

“This assumption is consistent with recent theoretical studies of the solar system’s evolution that suggest that asteroids rich in small, volatile molecules like water and carbon dioxide formed beyond Jupiter’s orbit before being transported to areas closer to the sun.”

Just announced by my workplace!
And no, I don’t teach in that department.
However, it does show the need for STEM students and researchers in Japan to improve their English. For every study like this published in English there are many more only published in Japanese. Lots of interesting research going on in Japan that people *outside* Japan need to know about!

The gag practically writes itself…
…but seriously, this is neat. One source of the X-Rays is the Sun (it also bounces off of Jupiter and Saturn). But there may be yet another source…perhaps the rings of Uranus or the planet itself.
And no, it’s not really pink. That’s just a Chandra X-ray image.
Shame, really.

Hazardous asteroid!? Call out Bruce Willis!
No worries. “Close to Earth” in this is 1.25 million miles. But it’s a great chance to find out more about the early solar system.

Critics of the Planet Nine claim said the apparent clustering of the discovered TNOs might only be because that’s where telescopes were looking or were most sensitive.

If you are looking to find evidence to prove your theory, it’s much easier to find what you’re looking for.
You should instead try to find evidence to disprove your theory, and then ask at least two more people you don’t know (or even better, generally disagree with) to try to find evidence to support your theory.
“Seek and ye shall find” is a terrible way to support a claim. Have the courage to challenge your beliefs.
Also, it’s Planet X, not 9. Pluto is a planet. So there, Neil deGrasse Tyson. :-p

Looks like Mars doesn’t spin perfectly on its axis. In fact, it wobbles.
And no one knows why.
This makes Mars only the second planet in our solar system to exhibit what’s called the “Chandler wobble.”
The other planet?
Why, Earth, of course.
(And, no, nobody knows why. Hmm. Chandler?)

Hey, everyone! If you look up at the right time, you can…
Uh. Yeah, anyway.

This family of comets originated from a large parent comet that broke up into smaller fragments well over a thousand years ago. The sungrazers continue to orbit around the sun today.

“As per the new simulations, it will take 100 billion years for any remaining planets to run off across the galaxy, leaving the dying Sun far behind.”
Pack your bags, folks!

Visible from the Americas, Australia and Asia, the “Beaver Moon” will pass through Earth’s outer shadow (penumbra) at 07:32 Universal Time, causing a slight penumbral lunar eclipse that will see 83% of the Moon visibly darken at 9:42 Universal Time…
