ESA celebrates ExoMars orbiter success, keeps vigil for lost lander

19 October 2016 Stephen Clark

A European-built orbiter designed to seek out the source of methane on Mars slipped into orbit around the red planet Wednesday after a seven-month interplanetary journey, but mission control lost contact with an experimental landing probe just before touchdown.

Eta Carinae star system revealed in unprecedented detail

19 October 2016 Astronomy Now

An international team of astronomers have used the Very Large Telescope Interferometer to image the Eta Carinae star system in the greatest detail ever achieved. They found new and unexpected structures within the binary system, including in the area between the two stars where extremely high velocity stellar winds are colliding.

Recently active lava flows from volcano Idunn Mons on Venus

19 October 2016 Astronomy Now

Planetary researchers at the German Aerospace Center (DLR) have pushed the limits of the data resolution from ESA’s Venus Express spacecraft. With this new technique, analysis of the top and eastern flank of 200-kilometre-wide volcano Idunn Mons in the southern hemisphere of Venus revealed an indication of geologically recent volcanism in this area.

Engine trouble keeping Juno in elongated orbit until December

18 October 2016 Stephen Clark

Ground teams are buying more time to study two sluggish valves inside the Juno spacecraft’s fuel pressurization system and postponing a major engine burn that was scheduled for this week to reshape the probe’s orbit around Jupiter.

Astronomers predict possible birthplace of Rosetta-probed comet 67P

18 October 2016 Astronomy Now

Canadian researchers have charted a path that most likely pinpoints the very origins of 67P/Churyumov-Gerasimenko, the comet studied intensively by ESA’s Rosetta spacecraft. Western University astronomers believe that 67P is made from primordial material and relatively new to the inner parts of our solar system, having only arrived about 10,000 years ago.

A saucer-shaped entry, descent and landing demonstrator separated from Europe’s ExoMars orbiter Sunday, beginning a three-day approach aiming to become the first European-built craft to set down on the red planet and return data.

Hubble reveals NGC 299 within the Small Magellanic Cloud

17 October 2016 Astronomy Now

It may be famous for hosting the Small Magellanic Cloud (SMC) and 47 Tucanae, the second brightest globular cluster in the night sky, but the southern constellation of Tucana (The Toucan) also possesses a variety of unsung cosmic beauties. One such beauty is NGC 299, an open star cluster located within the SMC just under 200,000 light-years away.

Discovering the X-ray treasures in Chandra’s archives

16 October 2016 Astronomy Now

Each year, NASA’s Chandra X-ray Observatory helps celebrate American Archive Month by releasing a collection of images using X-ray data. Each of these six new images — representing just a small fraction of the treasures that reside in Chandra’s unique archive — also includes data from telescopes covering other parts of the electromagnetic spectrum, such as visible and infrared light.
