This is a photo of the solar chromosphere, captured using a 6" telescope I modified to safely handle the intense heat from focusing the sun's powerful radiation
By isolating the bandpass, vivid atmospheric structure starts to emerge
That structure on the limb is 4 Earths tall!
Welcome home Reid, Victor, Christina, and Jeremy! 🫶
The Artemis II astronauts have splashed down at 8:07pm ET (0007 UTC April 11), bringing their historic 10-day mission around the Moon to an end.
Back in 1054, astronomers recorded a supernova as a bright new star that, for weeks, was visible even during the day!
The remnants of that supernova are the intricate filaments of the Crab Nebula, first observed by Hubble a quarter-century ago. Now, we have a new look ⬇️
A new meaning to finding yourself📍
Our Perseverance Mars rover can now pinpoint its location without help from operators on Earth. Read more about the tech that makes it possible: https://t.co/bOC4UeTnSe
A shot in the dark ✨
While most galaxies shine bright, a rare type remains nearly invisible — low-surface-brightness galaxies dominated by dark matter and containing only a scattering of faint stars.
CDG-2 is one such galaxy, detected by Hubble: https://t.co/osseWn8twF
Take an epic journey into a lost world in THE DINOSAURS, a new documentary series narrated by Morgan Freeman, premiering March 6.
From executive producer Steven Spielberg, Amblin Entertainment, and the award-winning team behind Life on Our Planet.
Made it.
At 6:42pm ET on Jan. 17, the stacked Artemis II rocket and spacecraft reached Launch Pad 39B after a nearly 12-hour journey from the Vehicle Assembly Building at @NASAKennedy in Florida.

3,000 light-years away is the Red Spider Nebula. Powerful stellar winds generate waves 62.4 billion miles high. The waves develop when gas is compressed and heated in front of the nebula, then emit radiation, seen here by the Hubble Space Telescope.
We are just weeks away from Artemis II, where we will send astronauts around the Moon—farther than any crew has traveled before.
The mission’s press kit is now available! Check it out: https://t.co/R3JaaG8lQU

Astronomers have used NASA’s IXPE telescope to measure a white dwarf star for the first time ever — revealing details about how it pulls in material from its companion star and how its powerful magnetic field shapes that process.

A team using @NASAHubble has made the first confirmed detection of a new type of astronomical object: a starless, gas-rich, dark-matter cloud, nicknamed Cloud-9. Here's what this object is teaching us about dark matter and the early universe: https://t.co/csCRXnzgDM
The results are in—Percy’s still got it 💪
Our Perseverance rover has spent nearly five years exploring Mars, and @NASAJPL engineers have determined it’s in excellent shape and can operate until at least 2031. More about the rover and what it studies: https://t.co/HvndZSwMn4
