    NASA’s TESS discovered its first Earth-size planet in a star’s habitable zone, the range of distances where conditions may be just right to allow the presence of liquid water on the surface. followed up and confirmed it.

    In February 1995, Hubble captured this image of a bow shock near the star LL Orionis in the Orion Nebula. It's formed as a strong "wind" of particles from the star collides with slow-moving gas in the nebula. For more information:

    🔭 Goddard scientist Al Kogut found a way to do Hubble-class science from a relatively inexpensive scientific balloon, and is well on the way to proving the concept.

    Space exploration is a profoundly human endeavor. On 's Day of Remembrance, we honor those who lost their lives while furthering exploration and discovery, and look to the stars in their honor.
