Astrophysicists from the Harvard-Smithsonian Center for Astrophysics examine orbit flips in exoplanet systems, presenting a previously unidentified mechanism whereby such interactions can completely flip the…
This newly released Hubble image shows spiral galaxy Messier 61, also known as NGC 4303. This new Hubble picture is the sharpest ever image of…
NASA’s WISE and Spitzer Space Telescope have discovered the coldest known brown dwarf, which is located 7.2 light-years away. NASA’s Wide-field Infrared Survey Explorer (WISE)…
A new study reveals that the chemistry of a star’s protoplanetary disc could influence the later composition of planetary atmospheres. Born in a disc of…
Amateur astronomers and astrophotographers have combined their optical data with the data from some of the world’s most sophisticated space telescopes to reveal new images…
Using data from the Sloan Digital Sky Survey to group together over half a million galaxies of all different colors, shapes, and masses, new research…
Using data from the Kepler spacecraft, researchers from the University of Washington confirm the first “self-lensing” binary star system. What looked at first like a…
Changes in T-cell behavior quickly occur in space, allowing researchers to more effectively study genetic and molecular changes associated with aging-related immune suppression. Telling someone…
This newly released Hubble image shows globular cluster Messier 5, which is located 24,500 light-years away. This sparkling jumble is Messier 5 — a globular…
Nearly completed, the VPHAS+ catalog will include stars and nebulae that are as much as 1500 times fainter than the ones in the older catalog,…
Using data from NASA’s Solar Dynamics Observatory, researchers have developed a new technique that opens the door for near real-time mapping of the sun’s roiling…
Astronomers have discovered the first Earth-size planet orbiting a star in the “habitable zone,” confirming that Earth-size planets exist in the habitable zones of other…
New research reveals that sudden speed jumps in the rotational velocity of pulsars have a minimum size, and that they are caused not by the…
This newly released Hubble image provides a cross-section view of the Universe, showing objects at different distances and stages in cosmic history. An image of…
Using data from meteorites that fell to Earth from Mars, scientists investigate the chemical composition of the Martian atmosphere throughout history, and learn whether the…
The European Southern Observatory reveals a new image of Gum 41, a cloud of hydrogen and newborn stars in the constellation of Centaurus. This new…
New research from astrobiologists at NASA’s Goddard Space Flight Center reveals that large amplitude, high frequency obliquity oscillations on Earth-like exoplanets can suppress the ice-albedo…
Using supercomputers like Stampede at the Texas Advanced Computing Center and Kraken at the National Institute for Computational Sciences, researchers try to predict and better…
