Did you know that the first landing of a robot on a small planetary body was done by @nasa ’s #NEARShoemaker on February 12, 2001, on asteroid Eros. Here is the last image taken, although instruments kept operating for weeks, gathering diagnostic data of this asteroid #nasa60th

The @NASAPersevere rover is carrying a small helicopter named Ingenuity. This @NASA_Technology demonstration could result in the Martian equivalent of a Wright Brothers moment. Learn how @NASAAero innovators contributed their expertise:

Congrats to the team! The @NASAHubble team has successfully switched to backup hardware on the telescope, including powering on the backup payload computer. Now, they are monitoring the hardware to ensure everything is working properly. More to come soon:

Wow! Look at this beautiful galactic dance. This image taken by @NASAHubble shows Arp 282, an interacting galaxy pair, experiencing tidal interaction, a phenomenon that occurs when an object’s gravity causes the other object to stretch or distort. More:

Our universe emits energy in many forms and by using telescopes like @chandraxray , @NASAHubble , @NASAWebb , and #IXPE we will have the tools to explore it. Take a look at the ways different types of light from ground and space telescopes can be combined:

Did you know stars can blow bubbles? The galaxy in this image is a hot star 45-times more massive than the Sun. A fierce stellar wind and intense radiation has blasted out the structure of glowing gas creating this cosmic bubble. 📸: @NASAHubble More:

With the required approval from Congress, NASA has been in discussions with China to explore the possibility of observing a signature of the landing plume of their lunar lander, Chang’e 4, using our @NASAMoon spacecraft's instrument. More on collaboration:

The time has come. As expected, @NASAKepler has run out of fuel. Throughout its lifetime, it has observed 500,000 stars & galaxies & has discovered 2,600+ planets beyond our solar system. Thank you for changing our view of the universe!

Did you know that there are 3,800+ confirmed planets outside our solar system? These worlds that orbit other stars are called exoplanets. We weren’t sure exoplanets even existed until the 1st one was confirmed not too long ago in 1995. More facts:

Life would not exist if it weren't for our planet's protective atmosphere. Humanity is able to explore the cosmos only because we're safeguarded on this spaceship we call Earth. Learn about the ways NASA studies & protects our home planet: Happy #EarthDay !
