Pluto probe provides appetiser for next week’s flyby

10 July 2015 Stephen Clark

Living up to promises that the view from New Horizons will only get better, the Pluto-bound spacecraft has again bested itself with a dazzling colour view of Pluto and Charon released Thursday.

Gigantic, early black hole could upend evolutionary theory

10 July 2015 Astronomy Now

Astronomers have spotted a super-sized black hole in the early universe that grew much faster than its host galaxy. The discovery challenges previous notions about the way host galaxies grow in relation to black holes and casts doubt on earlier suggestions that the radiation emitted by expanding black holes curtails the creation of stars.

9 July 2015 Astronomy Now

On the final day of NAM2015, science writer Kulvinder Singh Chadha investigates a new model that generates accurate predictions of irregularities within the Sun’s 11-year heartbeat, suggesting that solar activity could fall by 60 percent during the 2030s to ‘mini ice age’ conditions. Kulvinder also looks back at the lighter moments and highlights of a successful conference.

A “heart” from Pluto as New Horizons’ flyby begins

9 July 2015 Astronomy Now

Now just five days away from its close encounter with dwarf planet Pluto, NASA’s New Horizons spacecraft beams back the first image to be received since the 4 July anomaly that sent the spacecraft into safe mode, indicating that all systems appear to be functioning normally. The flyby sequence of science observations is officially underway.

8 July 2015 Astronomy Now

In his third report from the Royal Astronomical Society’s NAM2015, Kulvinder Singh Chadha examines the Sun in X-ray and ultraviolet wavelengths from three different spacecraft, dons a virtual reality planetarium headset, and investigates if the proposed James Webb Space Telescope (JWST) could discern Earth-sized worlds that are habitable.

In his second report from the Royal Astronomical Society’s National Astronomy Meeting 2015, Kulvinder Singh Chadha ponders the nature of dark matter and whether cosmic jets — jets of material from active galaxies travelling close to the speed of light — may correlate with dense regions of dark matter in the Universe.

The Royal Astronomical Society’s National Astronomy Meeting 2015 in Llandudno, Wales, 5—9 July
is the largest regular professional astronomy event in the UK and will see leading researchers from around the world presenting the latest work in a variety of fields. Kulvinder Singh Chadha reports from the conference.

Stellar fireworks predicted during rare pulsar encounter in 2018

6 July 2015 Astronomy Now

Astronomers are expecting high-energy explosions when pulsar J2032 swings close by its massive companion star in early 2018. The pulsar will plunge through a disc of gas and dust surrounding the star, triggering cosmic fireworks from radio wavelengths to the highest-energy gamma rays detectable.

Technical problem pauses Pluto probe’s science operations

5 July 2015 Stephen Clark

NASA’s New Horizons space probe, 10 days from a one-shot encounter with enigmatic Pluto, stopped collecting science data Saturday after a technical problem interrupted the spacecraft’s tightly-choreographed flight plan.

SOFIA in the right place at the right time for Pluto observations

4 July 2015 Astronomy Now

Currently operating out of Christchurch, New Zealand, the NASA/DLR SOFIA airborne 2.5-metre infrared telescope had to make last-minute flight path corrections to successfully secure observations of Pluto’s atmosphere as it occulted a distant star.
