We now offer the Cool It! card game in our Science Store. Cool It! is the new card game from UCS that teaches kids about the choices we have when it comes to climate change.
The X-ray light image of the cloud Cassiopeia A versus the visible light image. If you look very closely, you can see a small bright spot near the middle of the cloud in the X-ray image. Scientists say this may be a neutron star or black hole.

NASA Reveals First Images from Chandra
News story originally written on August 27, 1999

NASA revealed the first images from the Chandra X Observatory. Since first being deployed July 23, the Chandra X Observatory has had no problems. Included in the first set are images of a huge cloud with either a neutron star or black hole inside it.

NASA believes the powerful telescope will reveal black holes hiding in the universe. The Chandra takes images using X-rays instead of visual light. X-rays are usually released by really hot objects. Many of these objects cannot be seen with normal light, which means the Hubble Space Telescope cannot see them.
