In 2023, we brought a sample of an asteroid called Bennu to Earth, part of a plan to study remnants of our early solar system. These grains of rock have shown that the building blocks of life and the conditions for making them existed on Bennu's parent body 4.5 billion years ago. The Bennu samples contain amino acids — the building blocks of proteins — including 14 of the 20 that life uses to create proteins here on Earth. In addition, the samples contain all five of the nucleobases that encode genetic information in DNA and RNA.
nasa.gov/news-release/n…Graphic that shows all 20 proteinogenic amino acids, with those found in the Bennu samples highlighted in yellow, against a black background. Bennu, a gray, lumpy diamond-shaped asteroid, is in the background. Highlighted amino acids are: Alanine. Glutamic Acid, Leucine. Serine, Threonine, Asparagine, Glycine, Methionine, Aspartic Acid, Phenylalanine Tyrosine, Isoleucine, Proline, and Valine. Non-highlighted amino acids, which were not found in the Bennu sample, are: Arginine, Glutamine, Lysine, Tryptophan, Histidine, and Cysteine. Above each amino acid is its chemical structure.

The nucleobases, from left to right, are: Guanine, Cytosine, Adenine, Thymine, and Uracil. Each has its chemical structure depicted below it. Above the list of nucleobases is a portrayal of the double helix-stranded DNA. Below the list is a portrayal of the single-stranded RNA.

Does your brain ever feel like a black hole? We get it. Some days…weeks…it’s just like that.

#BlackHoleWeek is the perfect time to celebrate those times when all thoughts disappear behind the event horizon. Here, we’ve got 5 tips to tell if your brain has gone full black hole. Things go in, and they don’t come back out.

Black holes are so dense that gravity just below their event horizons is strong enough that nothing – not even light – can escape. This data visualization shows a complete revolution around a simulated black hole and its accretion disk following a path that is perpendicular to the disk. The black hole’s extreme gravitational field redirects and distorts light coming from different parts of the disk, but exactly what we see depends on our viewing angle. The greatest distortion occurs when viewing the system nearly edgewise. White text across the image reads "1. Things go in, and they don't come out."

Dr. Trena Ferrell keeps your friendly neighborhood space flight center friendly! 👋 She blends science and education to connect students, visitors, and citizen scientists with Goddard programs and resources as education & public outreach lead for NASA's Earth Science Division. Dr. Trena Ferrell sits at a... Trena came to Goddard in 2005, and today coordinates events and workshops across the country.

"I work with students from kindergarten through college. I want them to reach for the stars and realize that they can be scientists or engineers who work at NASA," she said. Trena Ferrell smiles and wa...

A lake frequented by dinosaurs turned fertile farmland now often holds something else—air pollution and haze. Why? 🧵

This image of the haze collected in Sichuan Basin in southwestern China was captured by NASA’s Terra satellite.

go.nasa.gov/3l80FTe Satellite image of the Sich... During winter in the Sichuan Basin, coal and wood burning for heat, industrial activity, vehicle emissions, and smoke from fires and dust storms can contribute to haze and poor air quality.

Are you seeking a cosmic connection? Someone to share your love of Germanic languages or extinct volcano exploration?

Our planetary profiles are just what you need ♥️.
For #ValentinesDay2020, see which solar system objects you would like to know better: solarsystem.nasa.gov The center of our solar system, the Sun is looking for someone to light up its life. Interests:

Spin classes - It spins once every 27 days.
Warm climates - The Sun’s core is 27 million degrees F.
Stargazing - It’s a star classified as a “yellow dwarf.”

♥️♥️♥️🌞

Happy Birthday #NASA. 60 has never looked better!🎉🎂

From the beginning, Goddard has worked to support our agency’s work of uncovering the universe 🌃.

Here are a few ways Goddard has helped along the way. #NASA60th It started with Dr. Robert Goddard! In 1926, he successfully tested the first rocket using liquid fuel 🚀🚀. Today he’s known as the “Father of Modern Rocketry.” #NASA60th

THREAD: Need a break from #BlackFriday, digging @NASA’s #BlackHoleFriday? Perfect, enjoy our Black Hole 101! ☄️ First the basics. A black hole is a region in space where the pulling force of gravity is so strong that light is not able to escape. Because of this, black holes are invisible. Only telescopes with special instruments can help find them.

Lasers. In. Space.
NASA’s got ‘em! Next year we launch a satellite with lasers, @NASA_ICESat2, to measure Earth’s changing ice #NASASocial To measure the height of ice, ICESat-2’s instrument ATLAS will send laser light to Earth, and time how long it takes to get back
