“Without a doubt the most interesting sample returned from the Moon!”

The oldest known unshocked rock retrieved from the Moon, called Troctolite 76535, was collected by #Apollo17 astronaut Harrison Schmitt. It’s at least 4.2 BILLION years old. @NASAMoon

I double-majored in physics and human rights at the University of Connecticut. I wasn’t interested in pursuing physics after college until I took my first astrophysics class with my first woman physics professor. She inspired me to pursue a career in astrophysics. /jcr

In the exciting days after a GRB, I am triggering telescopes, turning their data into a beautiful image of the explosion, and measuring how bright the explosion was. In a typical day, I study our observations of past GRBs to better understand their causes and how they work. /jcr
#NASAUniverse


I use observations from some of the world’s largest optical telescopes to better understand the universe’s most energetic explosions: gamma-ray bursts (GRBs). We can't predict GRBs, and their optical counterparts can fade in hours, so trying to catch them is quite exciting! /jcr

Science is a cycle of questions and answers … and sometimes a discovery shakes up what we know about the universe! #ICYMI, Swift and Fermi recently detected a gamma-ray burst that didn’t fit into established categories for these powerful events: go.nasa.gov/3YEaMib

One of the most exciting things you can hear in science is, "Huh, that's weird."


Hubble helped find evidence of two exoplanets (planets that orbit stars beyond our Sun) where water makes up a large fraction of the entire planet.

Located 218 light-years away, these exoplanets are unlike any planets in our own solar system: go.nasa.gov/3uUZF6y

🤝 Gemini VII, meet Gemini VI-A

The first-ever rendezvous of two spacecrafts with astronauts on board happened #OTD in 1965. This photo of the Gemini VII craft was taken by the crew of Gemini VI.

Some of the lunar samples collected during #Apollo17 were stored for 50 years to preserve them for future generations. NASA’s Apollo Next Generation Sample Analysis initiative is studying Apollo samples using new tools that weren't available decades ago. go.nasa.gov/3BBAHgx

Whoever decided they should wait 50 years hit it spot on. Just about the time we're heading back to the moon.


Scientists found “buried treasure," and the Cosmic Cliffs marked the spot. 🏴‍☠️

Remember this view from Webb’s first images? A deep dive has revealed young stars in an elusive stage of development — and may help us investigate how stars like our Sun form: go.nasa.gov/3hwWOh9
#JamesWebb

in reply to NASA

I asked #ChatGPT #AI how stars are made!

The generation of celestial bodies such as the sun can be attributed to the deity known as the Star Maker. This divine being imbued a nebulous conglomeration of gas and dust with the breath of life, causing it to undergo a process of gravitational contraction. As the nebula collapsed, the heat and pressure at its core became increasingly intense, culminating in the initiation of nuclear fusion reactions.

😉 Yay, Star Maker!



These young stars interact with their environments by taking in material and then ejecting some of it. The ejections, in the form of jets and outflows of matter, heat the surrounding hydrogen gas (H2, or molecular hydrogen), causing it to emit light.

Juno's Jovian Infrared Auroral Mapper (JIRAM) imager obtained this infrared view of Io in July. Brighter spots indicate higher temperatures in this image of the moon's highly volcanic surface.
#NASASolarSystem


Juno captured this view of Jupiter's moon Europa in September. During the flyby, Juno’s Microwave Radiometer (MWR) provided a look beneath Europa's icy crust to obtain data on its structure and temperature down to as deep as about 15 miles (24 kilometers) below the surface.

Smelly science!

Carbon Mapper will use data from @nasa's EMIT mission and current airborne and future satellite instruments to detect methane from waste sites. Methane is the source of roughly a quarter to a third of global warming caused by humans! go.nasa.gov/3WkjkZn

Observations from the EMIT mission and other NASA science instruments will be part of a global survey of point-source emissions of methane from landfills. The multiyear effort is being developed and conducted by the nonprofit Carbon Mapper organization.
