Astronomy Picture of the Day - 4000 Exoplanets

Explanation: Over 4000 planets are now known to exist outside our Solar System. Known as exoplanets, this milestone was passed last month, as recorded by NASA's Exoplanet Archive. The featured video highlights these exoplanets in sound and light, starting chronologically from the first confirmed detection in 1992 and continuing into 2019. The entire night sky is first shown compressed with the central band of our Milky Way Galaxy making a giant U. Exoplanets detected by slight jiggles in their parents-star's colors (radial velocity) appear in pink, while those detected by slight dips in their parent star's brightness (transit) are shown in purple. Further, those exoplanets imaged directly appear in orange, while those detected by gravitationally magnifying the light of a background star (microlensing) are shown in green. The faster a planet orbits its parent star, the higher the accompanying tone played. The retired Kepler satellite has discovered about half of these first 4000 exoplanets in just one region of the sky, while the TESS mission is on track to find even more, all over the sky, orbiting the brightest nearby stars. Finding exoplanets not only helps humanity to better understand the potential prevalence of life elsewhere in the universe, but also how our Earth and Solar System were formed.

Useless without pictures of the women on each one.

LOL, kidding, really cool.

If they are uninhabited we can take Dr. Strangelove's advice, " the women will have to be selected for their sexual characteristics which will have to be of a highly stimulating nature."

Exoplanets are like exoskeletons. They are planets covered in a large mechanical shell.

So we should bring lots of high heeled shoes to bargain with.

If one of these exoplanets is revolving around a star which goes nova, does the exoplanet become an ex-planet?

We don't know if life forms naturally given the right conditions--I wouldn't bet against it. But if there is life elsewhere, most of it may be of an extremely simple form. Supposedly life first appeared on earth four billion years ago, but the first multi-cellular life was not until 600 million years ago. More than three billion years with just one-celled forms of life.

"If one of these exoplanets is revolving around a star which goes nova, does the exoplanet become an ex-planet?"

Depends on whether the planet survives. Google says a planet orbiting Betelguise will lose at least 4km of it's surface, vaporized to space. Good chance it will be an ex-planet.

But if it survives, and is no longer orbiting a remnant star, then it's a "rogue" planet. Filled with beautiful women with white streaks in their hair and able to drain your powers and life force with a single touch.

It becomes exodebris.

(Damn; I missed the Perseids...)

Cool video, it was interesting to see them displayed that way.
We are discovering just how crowded this 鈥榦l galaxy really is.

Danny,
You forgot that the ratio, women to men, will be 10-1!
Ooh boy, is that great, or what? Never mind the mineshafts.

Yeah, at first glance that seems like a very good thing.
Second thought, I’m not so sure.
That is a lot of headaches.
On average, every 3 days someone will be going into PMS.
