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.

National Radio Astronomy Observatory (NRAO) 20 Dec 2018, 14:00 UTC As comet 46P/Wirtanen neared Earth on December 2, astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) took a remarkably close look the innermost regions of the comet’s coma, the gaseous envelope around its nucleus.
ESA Top News 20 Dec 2018, 10:25 UTC This image shows what appears to be a large patch of fresh, untrodden snow – a dream for any lover of the holiday season. However, it’s a little too distant for a last-minute winter getaway: this feature, known as Korolev crater, is found on Mars, and is shown here in beautiful detail as seen by Mars Express.
NCCR PlanetS 19 Dec 2018, 17:08 UTC Researchers at the Universities of Zurich and Cambridge have discovered a new, exotic class of planets outside our solar system. These so-called super-Earths were formed at high temperatures close to their host star and contain high quantities of calcium, aluminium and their oxides – including sapphire and ruby.
ALMA (Atacama Large Millimetre/Submillimetre Array) 18 Dec 2018, 19:13 UTC Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that two young stars forming from the same swirling protoplanetary disk may be twins — in the sense that they came from the same parent cloud of star-forming material. Beyond that, however, they have shockingly little in common.
ESA Top News 18 Dec 2018, 10:48 UTC Artist’s impression of the BepiColombo spacecraft in cruise configuration. In this viewing orientation, the Mercury Transfer Module is at the bottom, its ion thrusters firing, and its solar wings extending about 14 m either side of the module. The 7.5 m-long solar array of the Mercury Planetary Orbiter in the middle is seen extending to the top, the reverse side facing the viewer. The booms of the magnetometer and medium gain antenna are also seen. The Mercury Magnetospheric Orbiter sits inside the sunshield, which is visible at the top.
