Star formation on filaments in RCW106

27 February 2017 Stephen Clark

Stars are bursting into life all over this image from ESA’s Herschel space observatory. It depicts the giant molecular cloud RCW106, a massive billow of gas and dust almost 12,000 light-years away in the southern constellation of Norma, the Carpenter’s Square.

First evidence of rocky planet formation in Tatooine system

27 February 2017 Astronomy Now

Evidence of planetary debris surrounding a double sun, ‘Tatooine-like’ system has been found for the first time by a UCL-led team of researchers.

Mapping the family tree of stars

25 February 2017 Stephen Clark

Astronomers are borrowing principles applied in biology and archaeology to build a family tree of the stars in the galaxy. By studying chemical signatures found in the stars, they are piecing together these evolutionary trees looking at how the stars formed and how they are connected to each other.

The dawn of a new era for Supernova 1987A

24 February 2017 Stephen Clark

Three decades ago, astronomers spotted one of the brightest exploding stars in more than 400 years. The titanic supernova, called Supernova 1987A, blazed with the power of 100 million suns for several months following its discovery on Feb. 23, 1987.

Fermi space telescope finds possible dark matter ties in Andromeda

23 February 2017 Stephen Clark

NASA’s Fermi Gamma-ray Space Telescope has found a signal at the center of the neighboring Andromeda galaxy that could indicate the presence of the mysterious stuff known as dark matter. The gamma-ray signal is similar to one seen by Fermi at the center of our own Milky Way galaxy.

Nearby star is home to seven possibly-habitable planets

22 February 2017 Keith Cooper

Seven Earth-sized planets have been discovered orbiting a single ultra-cool dwarf star 40 light years away. Depending on atmospheric conditions, all seven could potentially be habitable, making the system a prime target for scientists hunting for another Earth.

The brightest, farthest pulsar in the universe

22 February 2017 Stephen Clark

ESA’s XMM-Newton has found a pulsar – the spinning remains of a once-massive star – that is a thousand times brighter than previously thought possible.

NASA’s Juno spacecraft to remain in current orbit around Jupiter

21 February 2017 Stephen Clark

Concerns about the health of the Juno spacecraft’s main engine have compelled NASA managers to keep the research probe in its current arcing, high-altitude orbit around Jupiter, a decision that will delay the full science return from the $1.1 billion mission but should still allow it to meet all predetermined objectives.
