Each year, NASA’s Chandra X-ray Observatory helps celebrate American Archive Month by releasing a collection of images using X-ray data in its archive.
The Chandra Data Archive is a sophisticated digital system that ultimately contains all of the data obtained by the telescope since its launch into space in 1999. Chandra’s archive is a resource that makes these data available to the scientific community and the general public for years after they were originally obtained.
A distant planet orbiting two red dwarf stars, found by its warping of spacetime, has been confirmed using observations from the NASA/ESA Hubble Space Telescope. The planet’s mass caused what is known as a microlensing event, where light is bent by an object’s gravitational field. This is the first circumbinary planet to be confirmed following detection of a microlensing event.
New Hubble observations suggest that an immense cloud of hydrogen gas was launched from the outer regions of the galactic disc around 70 million years ago and is plummeting back toward our galaxy at nearly 700,000 miles per hour. If this so-called “Smith Cloud” could be seen in visible light, it would span the sky with an apparent diameter 30 times greater than the size of the full Moon.
