Irradiated planets☢️
After a star goes supernova, its leftover core can rotate quickly, blasting pulses of radiation at intervals typically ranging from milliseconds to seconds. Orbiting pulsar planets would be hellish wastelands. We💚 them. exoplanets.nasa.gov/resources/…

Look on the bright side! No, really – see how the left side appears brighter in color?

It's caused by differences in sand cover. The western side of Egypt’s Lake Nasser is covered by sand and the eastern side is mostly rock. go.nasa.gov/3rJy6ib

Happy 24th birthday @chandraxray! Seen here just before being deployed from Space Shuttle Columbia (STS-93) #OTD in 1999, this powerful space observatory was initially expected to function for 5 years.

A ''dream'' planet?🩷
GJ 504 b is still glowing from the heat of its formation 160 million years ago. Astronomers say it is dark magenta, or the color of cherry blossoms. It orbits a star faintly visible to the unaided eye in the constellation Virgo. exoplanets.nasa.gov/news/116/m…

Scientists are studying how beavers impact ecosystems using @NASA_Landsat and Sentinel data, which help them compare across larger locations and over time. go.nasa.gov/3rszBkK

An unbeatable view

As the Apollo 11 astronauts make their way back home, they capture this image of Earth not long after leaving the Moon's gravitational sphere of influence.

This week at NASA:

• A swath of small satellites headed into orbit
• Our new hurricane-observing satellites viewed their first storms
• We kept our “A” for investing in small businesses

A total eclipse will sweep across North America on April 8, 2024. In preparation, we have awarded funding for three science teams to conduct citizen science investigations that will help study the Sun. Here are three ways you'll be able to take part: go.nasa.gov/43CDlO2

One small step.

OTD 54 years ago, Apollo 11 crewmembers became the first human beings to set foot on the lunar surface.

Today, we’re building on the legacy of Apollo as we prepare to establish a long-term human infrastructure on the Moon with #Artemis. #InternationalMoonDay

Rock on! Or...off?

After last year's #DARTMission, when @nasa intentionally crashed a spacecraft into an asteroid, Hubble has been observing the aftermath.

This Hubble image shows a few dozen boulders knocked off the asteroid by the collision: go.nasa.gov/44TUlQK

History was made. I wasn't even born in that decade. 🚀 "Apollo 11 launched from Cape Kennedy on July 16, 1969, carrying Commander Neil Armstrong, Command Module Pilot Michael Collins and Lunar Module Pilot Edwin "Buzz" Aldrin into an initial Earth-orbit of 114 by 116 miles. An estimated 650 million people watched Armstrong's televised image and heard his voice describe the event as he took "...one small step for a man, one giant leap for mankind" on July 20, 1969." nasa.gov/mission_pages/apollo/…


"That's one small step for [a] man, one giant leap for mankind."

Neil Armstrong's famous words upon stepping onto the Moon's surface were witnessed by 650 million people from around the globe #OTD in 1969. Watch ▶️ go.nasa.gov/46UfwEf

Do you have recollections of this day?
#NASAhistory

in reply to NASA

Yes, it's my earliest memory, watching on a B&W TV in the dining room with all the neighbors. They we went into the back yard and looked at the moon through our telescope, knowing there were humans on it.


Recovery teams met this week at the Department of Defense's Utah Test and Training Range to participate in field rehearsals in preparation for the retrieval of the sample return capsule from @nasa's OSIRIS-REx mission. Check out more images here 📸 flic.kr/s/aHBqjAN6Ys

the sample return capsule in The Andromeda Strain looked just like that.

Billions of years ago, a river coursed through the area where @NASAPersevere is now. The rocks it brought in hold stories not only of where they came from, but how they got there. What could they reveal about possible ancient life on Mars? Read more: go.nasa.gov/3K5IXJA

A large wildfire broke out on La Palma, the most northwesterly of the Canary Islands.

Fires here are common in the summer due to the island’s dry climate. @nasa's Aqua satellite captured the stream of smoke on July 15. go.nasa.gov/46S2hEb

What's going on with the hole in the ozone layer?

Thanks to a global effort to regulate ozone-depleting substances, the ozone hole is showing signs of recovery and is projected to return to a healthy level by mid-century. nasa.gov/esnt/2022/ozone-hole-…

Nice.

Just on time for humans to finally cop on to the fact that we have killed ourselves with our carbon excesses.

in reply to NASA

We could have done that with CO2, if we had wanted to.


Today’s students are tomorrow’s rocket scientists!

One of our #Artemis Student Challenges recently put undergraduate students’ skills to the test during the 14th First Nations Launch High-Power Rocket Competition.

Rock nerds rejoice! From big boulders to tiny pebbles, the ancient riverbed I’m exploring right now has it all. Washed in from upstream, these fragments can help my team uncover the river’s past and its potential for supporting ancient life. Read more: go.nasa.gov/3K5IXJA
