Using NASA’s Hubble and Kepler space telescopes, astronomers have uncovered tantalizing evidence of what could be the first discovery of a moon orbiting a planet outside our solar system.
This moon candidate, which is 8,000 light-years from Earth in the Cygnus constellation, orbits a gas-giant planet that, in turn, orbits a star called Kepler-1625. Researchers caution that the moon hypothesis is tentative and must be confirmed by follow-up Hubble observations.

A goblin lurks at the edge of our solar system. Far beyond Pluto, astronomers have found a new dwarf planet that follows the most distant orbit yet confirmed, reaching some 2300 times farther from the sun than Earth’s. Nicknamed “The Goblin” thanks to its discovery around Halloween 2015, 2015 TG387 takes 40,000 years to orbit the sun, researchers report online today on the preprint server arXiv.

We report the detection of a transiting planet around π Mensae (HD\,39091), using data from the Transiting Exoplanet Survey Satellite (TESS). The solar-type host star is unusually bright (V=5.7) and was already known to host a Jovian planet on a highly eccentric, 5.7-year orbit. The newly discovered planet has a size of 2.14± 0.04~R⊕ and an orbital period of 6.27 days. Radial-velocity data from the HARPS and AAT/UCLES archives also displays a 6.27-day periodicity, confirming the existence of the planet and leading to a mass determination of 4.82± 0.85~M⊕. The star’s proximity and brightness will facilitate further investigations, such as atmospheric spectroscopy, asteroseismology, the Rossiter-McLaughlin effect, astrometry, and direct imaging.

‘Everything about this flyby is tougher’: New Horizons just over 100 days from Ultima Thule

On New Year’s Day 2019, the spacecraft will come within 3,500 kilometers of 2014 MU69, an estimated 37-kilometer-wide object the mission team has nicknamed Ultima Thule. The encounter will take place 6.6 billion kilometers from Earth, where it takes more than 6 hours for radio signals traveling at the speed of light to reach NASA’s Deep Space Network.
There will only be one chance for New Horizons to perfectly aim its cameras and science instruments at Ultima Thule as it zips past at 14 kilometers per second, and there may be unforeseen hazards in the spacecraft’s path. Nevertheless, Jim Green, the director of NASA’s planetary science division, is looking forward to the drama.

Net successfully snares space debris

The RemoveDEBRIS satellite has successfully used its on-board net technology in orbit – the first demonstration in human history of active debris removal (ADR) technology.
The spacecraft began the experimental phase of its mission on Sunday 16 September, when it used a net to capture a deployed target simulating a piece of space debris.
[…]
In the coming months, RemoveDEBRIS will test more ADR technologies: a vision-based navigation system that uses cameras and LiDaR technology to analyse and observe potential pieces of debris; the first harpoon capture technology used in orbit; and a drag-sail that will finally bring RemoveDEBRIS into the Earth’s atmosphere where it will be destroyed, bringing its mission to a close.

Toward the middle of 2012, a long standing solar filament suddenly erupted into space producing an energetic Coronal Mass Ejection (CME). The filament had been held up for days by the Sun’s ever changing magnetic field and the timing of the eruption was unexpected. Watched closely by the Sun-orbiting Solar Dynamics Observatory, the resulting explosion shot electrons and ions into the Solar System, some of which arrived at Earth three days later and impacted Earth’s magnetosphere, causing visible aurorae. Loops of plasma surrounding an active region can be seen above the erupting filament in the featured ultraviolet image. Although the Sun is now in a relatively inactive state of its 11-year cycle, unexpected holes have opened in the Sun’s corona allowing an excess of charged particles to stream into space. As before, these charged particles are creating auroras.

ESO’s Very Large Telescope (VLT) has achieved first light with a new adaptive optics mode called laser tomography — and has captured remarkably sharp test images of the planet Neptune, star clusters and other objects. The pioneering MUSE instrument in Narrow-Field Mode, working with the GALACSI adaptive optics module, can now use this new technique to correct for turbulence at different altitudes in the atmosphere. It is now possible to capture images from the ground at visible wavelengths that are sharper than those from the NASA/ESA Hubble Space Telescope. The combination of exquisite image sharpness and the spectroscopic capabilities of MUSE will enable astronomers to study the properties of astronomical objects in much greater detail than was possible before.
