In a few billion years, our aging Sun will run out of hydrogen fuel in its core and begin to swell, eventually engulfing Mercury, Venus, and probably Earth itself. Known as the red giant phase, this is a normal step in a mid-sized star’s life cycle, when it swells to hundreds of times its usual size. There are plenty of red giants in the night sky, but astronomers have never caught one in the act of swallowing its planets — until now.

Pack your stuff, folks…

The photo is an artist’s depiction btw. The article describes how the astronomer discovered that star was eating its own planet.

Just to keep things in perspective…

Scientists detect small pockets of carbon dioxide-rich liquid water in a meteorite dating from the early solar system

“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!

New Earth discovered only 70,000 years away

Welp, it’s official. NASA announced they have confirmed another “Earth” (really, an “Earth-like planet” simply means it has enough water and is in the right orbit from its star to hypothetically support life).

Too bad it’s 500 light years away, which currently would take us a mere 70,000 years to reach.

But it’s a start…

Earthrise: Fifty years and counting (Don’t count on it)

“To really think about ourselves as citizens of Earth is something that I think we’re still working toward,” Jacob Haqq-Misra, a research scientist at Blue Marble Space Institute of Science, told Space.com. “[Seeing this image] may be enjoyable and fun and awe-inspiring, and you might think about it later that day, but I don’t think most people have a perception of ‘I’m a citizen of Earth’ when they’re driving to work.”

He’s curious how potential future space developments — establishing a human presence on Mars, or discovering extraterrestrial intelligence, for example — might make that Earthling perspective easier to grasp by creating a group to contrast it against.

That’s us: the forever simian, defining ourselves in contrast to what we aren’t as opposed to what we could be.

So what would happen if some of us became Martians, Venusians, or Jovians? Hmmm…
