The Dynamic Duo: Jupiter’s Independently Pulsating X-ray Auroras Jupiter’s intense northern and southern lights, or auroras, behave independently of each other according to a new study using NASA’s Chandra X-ray and ESA’s XMM-Newton observatories.

Chandra Reveals the Elementary Nature of Cassiopeia A Due to its unique evolutionary status, Cassiopeia A (Cas A) is one of the most intensely studied of these supernova remnants.
Kepler’s Gaze Shifts Toward New Targets — Supernovae, the ‘Beehive Cluster’ and Earth The sixteenth observing campaign of the Kepler spacecraft’s K2 extended mission is now underway. The campaign has prospects for discoveries among 30,000 objects in the direction of the constellation Cancer. The cartoon illustrates some of the objects of interest that Kepler is
NASA Hosts Media Teleconference to Announce Latest Kepler Discovery NASA will host a media teleconference at 1 p.m. EST Thursday, Dec. 14, to announce the latest discovery made by its planet-hunting Kepler space telescope.
Exoplanet Discoveries Today, as shown in figure 10, we know of over 3,500 confirmed exoplanets, with more than 2,500 of those found in the Kepler data. These planets range in size from larger than Jupiter to smaller than Earth. In just a couple decades, thanks largely to Kepler, we have gone from suspecting exoplanets existed
Planetary Systems by Number of Known Planets This figure shows the number of systems with one, two, three, planets, etc. Each dot represents one known planetary system. We know of more than 2,000 one-planet systems, and progressively fewer systems with many planets. The discovery of Kepler-90i, the first known exoplanet system with eight planets, is
Could Kepler-90 Have More Planets? This graphic shows that a small area around the Kepler-90 system, on the left, has been searched by the Kepler space telescope. Compared to our solar system, where we know of planets farther out, it is possible that Kepler-90 has even more planets. If planets (in the blue area) do
Kepler-90 Planets Orbit Close to Their Star Kepler-90 is a Sun-like star, but all of its eight planets are scrunched into the equivalent distance of Earth to the Sun. The inner planets have extremely tight orbits with a “year” on Kepler-90i lasting only 14.4 days. In comparison, Mercury’s orbit is 88 days. Consequently, Kepler-90i has
Kepler-90 System Planet Sizes The Kepler-90 planets have a similar configuration to our solar system with small planets found orbiting close to their star, and the larger planets found farther away.
Artificial Intelligence, NASA Data Used to Discover Eighth Planet Circling Distant Star Our solar system now is tied for most number of planets around a single star, with the recent discovery of an eighth planet circling Kepler-90, a Sun-like star 2,545 light years from Earth. The planet was discovered in data from NASA’s Kepler Space
