Exciting space-discovery alert!

Gliese 12 b is an Earth-size planet orbiting in the temperate zone around a nearby, stable red dwarf star. It's a Rosetta Stone world that will tell us a lot about how many superficially earthlike planets actually have the right conditions for life.

Are we rare? Are we common? Let's find out.

Many stories about newfound planet Gliese 12b (including the news release from the Royal Astronomical Society, sad to say) are full of errors.

We have NO idea yet what conditions are like there. That's what makes it so exciting! This is the kind of discovery that will provide big answers.

How do multiple planets line up in the sky as is expected around June 3?

The planets must be located on the same side of the line from earth to the Sun. The planets lie in the plane of ecliptic and therefore follow the path that the Sun travels on any given day as seen from earth; they always appear lined up along that arc.

So, all besides Venus will be present in the pre-dawn sky, but Jupiter and Mercury will be very low, Uranus and Neptune require binocs.

This morning, I woke up the kids by playing Mars, the Harbinger of War by Gustav Holst. Sounded like we were getting attacked by the Empire.

From a 1929 book on Child's Geography:
"But the World still kept on cooling and cooling, and as it cooled it shrank and shriveled and wrinkled and crinkled and puckered like the outside of a prune. You know a prune was once smooth and round when it was a plum. These little wrinkles and crinkles rose up out of the ocean and were the continents and mountains, so you see how big the wrinkles and crinkles really are."

A COSMIC ARROW PIERCED PLUTO'S HEART — IS IT STILL THERE BENEATH THE SURFACE?

A giant impact likely formed Pluto’s heart-shaped basin, Sputnik Planitia. A big chunk of the impactor’s core might still be buried under the ice.

Hey Mastodonians,

A new 'Remembering Cassini' episode is now posted on "Coming of Age in the Solar System".

It's called 'Entering the House of Saturn' ... which is what Cassini did 20 years ago today.

Astronomers think they’ve detected an extremely rare, luminous phenomenon known as “glory” in the hellish atmosphere of a distant exoplanet. The discovery would be the first time one of these rainbow-colored light shows has been seen outside of our solar system. Live Science reports: https://flip.it/RiSqJN

At mid-eclipse tomorrow, when the daylight sky turns dark, look for planets near the sun. Venus will be the brightest one. Jupiter will be 2nd-brightest. You might even see Mercury, Saturn and Mars.

Thirty years after the first exoplanets were discovered, hundreds of additional exoplanets have been identified within the “habitable zone,” a place where liquid water and maybe even life may exist. The MIT Press Reader asks, could a self-sustaining starship carry humans to distant worlds? https://flip.it/0q093h

I took another shot on processing the same data. The result is (hopefully) better.

On March 23, I experienced a rare event... a clear sky... so despite 99% Moon and my Bortle 7 sky, I went for it.

Saturn's moon Enceladus top target for ESA

"A fresh, icy crust hides a deep, enigmatic ocean. Plumes of water burst through cracks in the ice, shooting into space. An intrepid lander collects samples and analyses them for hints of life."
