NASA’s Transiting Exoplanet Survey Satellite’s four cameras have captured a razor-sharp “first light” image of the southern sky, demonstrating the photographic prowess needed to hunt down planets around nearby stars.
Extended oval storms known as “brown barges” are occasionally seen in Jupiter’s North and South Equatorial Belts, but they tend to blend into the surrounding area and are difficult to spot. NASA’s Juno spacecraft recently captured a clear view of a brown barge in the southern belt.
By measuring a star’s age and chemical makeup, astronomers can determine where a sun originated in the galactic disk before migrating outward. The Sun, it turns out, likely formed about 2,000 light years closer to the Milky Way’s core.
The Hubble Space Telescope is re-visiting six huge galaxy clusters, taking wide-angle views to help astronomers understand more about how galaxies were distributed across the early universe and what governed their evolution.
Artificial intelligence algorithms found 72 previously undetected fast radio bursts in a source 3 billion light years from Earth, demonstrating a powerful new tool for radio astronomers faced sifting through enormous amounts of data.
The European Southern Observatory’s Very Large Telescope captured a sublime view of galaxy NGC 3981 some 65 million light years from Earth, showing stretched out spiral arms that may indicate past gravitational encounters with other nearby galaxies.
The merger of two neutron stars, observed in August, created two powerful jets streaming away into space at nearly the speed of light, in agreement with theoretical predictions and shedding new light on gamma ray bursts.
The Hubble Space Telescope captured this spectacular view of Saturn last June, showing six of the ringed planet’s moons, during an ongoing study of outer planet atmospheres. This view expands on an earlier version posted here in July.
NASA’s Dawn spacecraft, almost out of fuel for maintaining its orientation and aiming its antenna toward Earth, is nearing the end of its life after a trail-blazing 11-year mission orbiting the asteroid Vesta and the dwarf planet Ceres.
