New Horizons 2 Jan 2019, 05:02 UTC Scientists from NASA's New Horizons mission released the first detailed images of the most distant object ever explored — the Kuiper Belt object nicknamed Ultima Thule. Its remarkable appearance, unlike anything we've seen before, illuminates the processes that built the planets four and a half billion years ago.
New Horizons Successfully Explores Ultima Thule:NASA Spacecraft Reaches Most Distant Target in History1 Jan 2019, 05:11 UTC NASA's New Horizons spacecraft flew past Ultima Thule in the early hours of New Year's Day, ushering in the era of exploration from the enigmatic Kuiper Belt, a region of primordial objects that holds keys to understanding the origins of the solar system.
ALMA (Atacama Large Millimetre/Submillimetre Array) 31 Dec 2018, 16:08 UTC Using observations from the Atacama Large Millimeter/submillimeter Array (ALMA) in Chile, researchers have observed, for the first time, a warped disk around an infant protostar that formed just several tens of thousands of years ago. This implies that the misalignment of planetary orbits in many planetary systems, including our own, may be caused by distortions in the planet-forming disk early in their existence.The planets in the Solar System orbit the Sun in planes that are at most about seven degrees offset from the equator of the Sun itself. It has been known for some time that many extrasolar systems have planets that are not lined up in a single plane or with the equator of the star. One explanation for this is that some of the planets might have been affected by collisions with other objects in the system or by stars passing by the system, ejecting them from the initial plane.However, the possibility remained that the formation of planets out of the normal plane was actually caused by a warping of the star-forming cloud out of which the planets were born. Recently, images of protoplanetary disks, rotating disks where planets form around a star, have in fact showed such ...
Isaac Newton Group of Telescopes (ING) 26 Dec 2018, 14:00 UTC Comet 46P/Wirtanen photographed by Abel de Burgos Sierra on the night of 16th December 2018 at perihelion, from the vicinity of the Isaac Newton Telescope (INT).
New Horizons 22 Dec 2018, 05:17 UTC New Horizons carried out its last trajectory correction maneuver on approach to Ultima Thule last week, a short thruster burst to direct the spacecraft closer to its precise flyby aim point just 2,200 miles (3,500) above the mysterious Kuiper Belt object at 12:33 am EST on Jan. 1.
NASA's Jet Propulsion Laboratory News and Features 21 Dec 2018, 19:07 UTC The December 2018 close approach by the large, near-Earth asteroid 2003 SD220 has provided astronomers an outstanding opportunity to obtain detailed radar images of the surface and shape of the object and to improve the understanding of its orbit.
NASA's Goddard Space Flight Center 21 Dec 2018, 15:00 UTC This festive NASA Hubble Space Telescope image resembles a holiday wreath made of sparkling lights. The bright southern hemisphere star RS Puppis, at the center of the image, is swaddled in a gossamer cocoon of reflective dust illuminated by the glittering star. The super star is ten times more massive than the Sun and 200 times larger.
NASA's Goddard Space Flight Center 20 Dec 2018, 18:00 UTC In science fiction, explorers can hop in futuristic spaceships and traverse half the galaxy in the blink of a plot hole. However, this sidelines the navigational acrobatics required in order to guarantee real-life mission success. In 2021, the feat of navigation that is the Lucy mission will launch. To steer Lucy towards its targets doesn’t simply involve programming a map into a spacecraft and giving it gas money – it will fly by six asteroid targets, each in different orbits, over the course of 12 years.
