As the New Horizons spacecraft flew by Jupiter #OTD in 2007, the most volcanically active body in our solar system didn't disappoint: Tvashta, a volcano on Jupiter's moon Io, was caught spewing a plume 200 miles above the surface! More about Io: go.nasa.gov/41vbEXP

By creating Earth's conditions from 4 billion years ago, scientists can narrow the chemical reactions that could have taken place then – including those that may have been critical to the emergence of life here, or that might signal life elsewhere. go.nasa.gov/3Zx7JYF

In 1604, astronomers like Johannes Kepler saw a supernova in Earth's sky. (This one is now named for him!) Star explosions eject material at 20 million+ mph/32M kph. The extreme brightness may only last for seconds, but the remnants remain for millennia. go.nasa.gov/3EKMryz

Before its mission ended in 2018, the space telescope named for Kepler would go on to discover more than 60 supernovae. We're *still* finding exoplanets in Kepler's data (3,251 so far)! go.nasa.gov/3ZshIhH

Meet the woman behind early @NASA_Landsat images: Dr. Valerie L. Thomas.

A self-taught programmer, she managed the development of Landsat image processing. Her work in the '70s helped show that satellite imagery could be used to support agriculture. go.nasa.gov/3EJMPgT #BHM

NASA astronaut and US Air Force Colonel Alvin Drew performed his first spacewalk #OTD in 2011, making repairs and upgrades to the @Space_Station during STS-133. In this photo from the 12-day mission, he's seen in the station's newly-installed Permanent Multipurpose Module. #BHM

what kind of experiences would he have gone through in the station during these 12 months?


Triples is best.

This Webb image features a special galaxy that appears 3 times. Why? There's a galaxy cluster here whose mass and gravity are so great that time and space around it gets warped. This magnifies, multiplies, and distorts galaxies behind it: esawebb.org/images/potm2302a/

Yassified to maintain anonymity? More like magnified to remove anonymity.

On his birthday, we celebrate the late Chris Kraft, who served as @nasa's first flight director. From America's first crewed missions to space to the Apollo Moon landings, he played a vital role in some of the most iconic moments in space history. go.nasa.gov/3Y0S9Dg

A once-forgotten exoplanet was resurrected, then dismissed, then resurrected again, and now appears doomed. Kepler-1658 b simply can't seem to catch a break. It now appears to be spiraling toward its host star – and will likely crash in ~3 million years. go.nasa.gov/3KIDV79

What do all these Hubble images have in common?

They show the aftermath of stars that died in a bright, powerful explosion known as a supernova.

In a supernova, a star’s contents fling out into space at speeds of up to 25,000 miles (15,000 to 40,000 km) per second!
#Hubble



These supernova remnants are made of material from the exploded star and any interstellar material it sweeps up in its path. Read more about supernova remnants and other types of nebulae: go.nasa.gov/3EILHKu

Check out @NASAUniverse for more supernova content all week!

5272!
22 exoplanets join the known worlds, bringing the confirmed total to 5,272. All 22 were discovered using microlensing, where light from a distant star is bent and focused by gravity as a planet passes between the star and Earth. go.nasa.gov/3kAwOmD

Strong earthquakes in Türkiye on Feb. 6 left many areas without electric power.

These maps show light around Antakya before (left) and after the earthquakes (right). Maps are from the Black Marble HD product, using @nasa @noaa Suomi-NPP satellite data. go.nasa.gov/3xTvQVw

The second pair of maps (below) show that some nighttime lights returned between February 8 and 9, but widespread outages persisted in much of the region surrounding Antakya in Türkiye.
