New worlds are born in the eye of a storm: These ALMA images show an inner disk where planets are forming, and a huge hurricane of gas & dust surrounding it. (For context, the storm is about 30x as big as Pluto's orbit around the Sun.)

The Hubble telescope used the Moon as a mirror to see if we could detect life on another Earth. Result: We could kinda sorta see ozone, an inconclusive life signature.

Baby stars hatch from "eggs" made of molecular gas. And the ALMA observatory found a whole nest of them in the constellation Taurus.

Aurora, relativistic electrons & a blast of lightning over Jupiter's north pole seen by @NASAJuno . The lightning may be triggered by storms of ammonia-water "mushballs."

Seriously, there are enormous storms of ammonia-laced mushballs on Jupiter.

Paleontologists have solved the riddle of Tanystropheus, a bizarre dinosaur-era reptile that had 3x as much neck as body.

Tanystropheus is so bizarre that for a long time nobody was sure if it lived on land, sea, or air. If it were around today...it would be quite a sight along the coast.

"It probably is the most remarkable fossil reptile that there is." -- paleontologist Nick Fraser at National Museums Scotland

Paleontology bullshit is technically known as coprolite.

This is the sharpest movie of the Sun ever made. Even at this fine resolution, the scale is enormous; each plasma cell here is about the size of Texas. via @NatSolarObs 

Wow wow: Dust, stars, and cosmic rays swirling around Comet 67P, captured by the probe (+ amazing processing by )

NASA commanded Voyager 1 to fire its thrusters for the first time in 37 years. 13 billion miles away, off in interstellar space, the probe responded perfectly.

I see versions of this nonsense claim all the time. This one went hugely viral. So let's dig into the actual numbers, cars versus volcanoes. (1/x)

Earth's magnetic field is weakening over South America, creating a hazard zone for low-orbiting satellites. It's a sign of little-understood changes happening in our planet's core.

Glowing lava inside Chile's Villarrica Volcano created this searchlight through a snowstorm, with the Large Magellanic Cloud in the background. What a shot! (Credit: Cristobal Saavedra Escobar)

India's @isro  lost contact with the Vikram lander just 2.1 km above the lunar surface--so close. Important to remember that the Chndrayaan-2 orbiter and its 8 instruments are safely orbiting the Moon.

Migrating swarm of stingrays (a "fever" of rays). Not Photoshopped. Not an Escher drawing.

The Arecibo telescope in Puerto Rico just bounced radar off a spinning, mile-wide rock, 5 million miles away, moving at 20,000mph...and we got pictures back. These observations amaze me every time.
