Green moon on April 20, 2016? Not true

No, there won’t be a green moon on April 20, 2016 … or on May 29. Some possible origins of this latest urban legend.

Why are these black hole jets aligned?

The only way for this alignment to exist is if the supermassive black holes in this part of space are all spinning in the same direction.

Kepler is OK! Spacecraft recovered from emergency

Kepler mission engineers still aren’t sure why the planet-hunting spacecraft went into Emergency Mode last week.

Stars strip atmospheres of super-Earths

The planets are 2-10 times as massive as Earth. They orbit near their stars and receive some 650 times the radiation that Earth receives from our sun.

In October 2013, Cassini flew high above Saturn, looking down toward its north pole. It took a series of shots that were then assembled into this amazing mosaic by software engineer Gordan Ugarkovic.

Planet 9 not affecting Cassini at Saturn

“Although we’d love it if Cassini could help detect a new planet, we don’t see any perturbations in our orbit that we cannot explain with our current models,” said Cassini project manager Earl Maize.

This computer-simulated image shows a supermassive black hole at the core of a galaxy. The black region in the center represents the black hole’s event horizon, where no light can escape the massive object’s gravitational grip. The black hole’s powerful gravity distorts space around it like a funhouse mirror. Light from background stars is stretched and smeared as the stars skim by the black hole.

Supermassive black holes everywhere?

A near-record supermassive black hole discovered in a sparse area of the local universe suggests these monster objects might be more common than once thought.

What is earthshine?

That glow over the unlit part of a crescent moon – called earthshine – is light reflected from Earth.

Supernovae showered Earth with radioactive debris

The supernovae may have been less than 300 light-years away. The evidence comes from radioactive iron-60, found in ocean sediments and crust.

SETI turns focus to 20,000 red dwarf stars

Astronomers with the Search for Extraterrestrial Intelligence had their reasons for ignoring red dwarf stars in the past. But now that thinking has changed.

Asteroid swept within moon’s distance April 5

Astronomers did know in advance that asteroid 2016 FW13 would pass closely – but safely – on April 5, 2016. Check out a photo from the Virtual Telescope Project.
