The Planet Building Mystery

30 October 2017

Open University researchers have been investigating exactly how planet formation starts. Why do we need to know how planets form? Planets form as a by-product of star formation. Similar to asteroids, comets, and our Moon, planets are basically the left-over “junk” that isn’t incorporated into the star itself. However, planets (and other small bodies in […]

What formed the recent Martian landscape? Latest research might have the answer

27 October 2017

Scientists from the OU have discovered a new phenomenon that could explain the long-debated mystery of how recent land features on Mars are formed in the absence of significant amounts of water. Dr Jan Raack explains more: What is this research all about? “Experiments carried out in our Mars Simulation Chamber, which is able to […]

Private companies are launching a new space race – here’s what to expect

4 October 2017

The space race between the USA and Russia started with a beep from the Sputnik satellite exactly 60 years ago (October 4, 1957) and ended with a handshake in space just 18 years later. The handshake was the start of many decades of international collaboration in space. But over the past decade there has been […]

Cassini crashes: it’s time for a new mission to explore the possibility of life on Saturn’s moons

15 September 2017

NASA’s Cassini mission has made its “death plunge” into the swirling clouds of Saturn after 20 years of exploring the planet and its moons. It’s been amazingly successful, making headlines with groundbreaking discoveries throughout its journey. But today the headlines are more like obituary notices, looking back at the mission’s spectacular achievements. Cassini discovered new […]

Scientists find some of Mars’ youngest volcanoes – and discover they could have supported life

26 July 2017

4000 km wide view of Mars’ (colour-coded topgraphy) Coprates Chasma. NASA/USGS/ESA/DLR/FU Berlin (G Neukum), CC BY-SA It may seem that Mars was once a much more exciting planet. True, there are dust storms and possible water-seeps occurring today, but billions of years ago it was a dramatic place with huge volcanoes, a giant canyon […]

The BepiColombo spacecraft is ready to solve the many mysteries of Mercury

11 July 2017

The €1.65 billion BepiColombo spacecraft is now being unstacked for final tests after being displayed in its launch configuration to the world’s press at the European Space Agency’s Space Technology and Research Centre. The six-metre high assembly will soon be shipped to Kourou in French Guyana where it is anticipated to launch in October 2018. […]

Crumbling comet? The great debate about whether Rosetta rock 67P is breaking apart

21 March 2017

It is almost six months since the Rosetta spacecraft completed its operations in a controlled dive onto the surface of comet 67P/Churyumov-Gerasimanko. The landing, after which Rosetta could no longer communicate with Earth, may have marked the end of data collection from the comet – but not the end of news about 67P. The archive […]

Organic molecules found on giant asteroid Ceres – why that’s such a huge deal

17 February 2017

Sometimes, I think scientists are just that little bit too modest. A new paper in Science has a humdinger of a title: “Localized aliphatic organic material on the surface of Ceres”. It doesn’t exactly trip off the tongue and may not even seem that important. But what the researchers have discovered is a huge deal. […]

How old is our moon

12 January 2017

Most scientists agree that the Earth has pretty much always had its moon. Details of the moon’s composition (in particular the “isotopic mixture” of heavier and lighter versions of various elements) are too similar to the Earth’s for it to have been captured from somewhere remote. However, some compositional details differ enough to rule out […]

Study sheds light on violent asteroid crash that caused mysterious ‘crater rings’ on the moon

8 November 2016

Some 3.8 billion years ago, the moon was a dangerous place – constantly bombarded with asteroids and comets. Our celestial neighbour still bears the scars of this time, in the shape of craters. The biggest of these are called basins, and one is the mysterious, 930km-diameter Orientale Basin, which looks like a bull’s eye with […]
