12.05.11 - This artist's conception illustrates Kepler-22b, a planet known to comfortably circle in the habitable zone of a sun-like star. It is the first planet that NASA's Kepler mission has confirmed to orbit in a star's habitable zone - the region around a star where liquid water, a requirement for life on Earth, could persist. The planet is 2.4 times the size of Earth, making it the smallest yet found to orbit in the middle of the habitable zone of a star like our sun. Scientists do not yet know if the planet has a predominantly rocky, gaseous or liquid composition. It's possible that the world would have clouds in its atmosphere, as depicted here in the artist's interpretation.

Astronomers Find Dark Energy May Vary Over Cosmic Time

A new study using data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton suggests that dark energy may have varied over cosmic time, as reported in our latest press release. This artist’s illustration helps explain how astronomers tracked the effects of dark energy to about one billion years after the…

Warming Seas May Increase Frequency of Extreme Storms

A new NASA study shows that warming of the tropical oceans due to climate change could lead to a substantial increase in the frequency of extreme rain storms by the end of the century. The study team, led by Hartmut Aumann of NASA’s Jet Propulsion Laboratory in Pasadena, California, combed…

NASA’s Juno Spacecraft Tracks Giant Jupiter Storms

A giant, spiraling storm in Jupiter’s southern hemisphere is captured in this animation from NASA’s Juno spacecraft. The storm is approximately 5,000 miles (8,000 kilometers) across. The counterclockwise motion of the storm, called Oval BA, is clearly on display. A similar rotation can be seen in the famous Great Red…

NASA’s NICER Mission measure light echoes from New Black Hole

Scientists have charted the environment surrounding a stellar-mass black hole that is 10 times the mass of the Sun using NASA’s Neutron star Interior Composition Explorer (NICER) payload aboard the International Space Station. NICER detected X-ray light from the recently discovered black hole, called MAXI J1820+070 (J1820 for short), as…

Perspective view of Korolev crater This image from ESA’s Mars Express shows Korolev crater, an 82-kilometre-across feature found in the northern lowlands of Mars. This oblique perspective view was generated using a digital terrain model and Mars Express data gathered over orbits 18042 (captured on 4 April 2018), 5726, 5692, 5654, and 1412. The crater itself is centred at 165° E, 73° N on the martian surface. The image has aresolution of roughly 21 metres per pixel. This image was created using data from the nadir and colour channels of the High Resolution Stereo Camera (HRSC). The nadir channel is aligned perpendicular to the surface of Mars, as if looking straight down at the surface. Released 20/12/2018 11:00 am Copyright ESA/DLR/FU Berlin, CC BY-SA 3.0 IGO
