The ARES plane soars over the Martian surface (Illustration: NASA)
The LIGO project's two observatories, including this one in Hanford, Washington, US, will join forces with the Virgo observatory in Italy and Germany's GEO 600 to hunt for gravitational waves (Image: LIGO Laboratory)
A map of the cosmic microwave background made by NASA's WMAP satellite shows density fluctuations in the early universe – regions of higher density were slightly warmer than voids. Similar maps by Planck may reveal the existence and shape of extra spatial dimensions (Image: NASA/WMAP Science Team)
Protons accelerated by our black hole's magnetic fields slam into nearby hot gas (red), producing high-energy gamma rays (Image: NASA/CXC/MIT/F K Baganoff et al)
A basketball-size robot sits on the surface of an asteroid after unfolding its spherical shell, while its parent spacecraft hovers in the background (Illustration: Ball Aerospace)
Relatively simple technology suffices to take out a satellite the way the Chinese government apparently did last week, space weapons analysts say. Essentially any country that can put a satellite in orbit could launch a weapon to destroy one.
The brightest supernova ever seen appears as a dark spot (arrow) in this negative infrared image taken by the Palomar 5-metre telescope. The other dark spot at centre is the host galaxy’s core (Image: E Ofek et al/Caltech/Palomar Observatory)
Saturn’s rings glow especially bright in this enhanced-colour mosaic from the Cassini spacecraft, assembled from images taken while the Sun was hidden behind Saturn itself (Image: NASA/JPL/Space Science Institute)
Slices through the Tagish Lake meteorite show hollow globules of organic matter, labelled G in these electron microscope images (K Nakamura-Messenger/NASA/JSC)
Loops of hot plasma trace the Sun's curving magnetic field lines in this frame from a video of the Sun made by JAXA's Hinode spacecraft (Image: JAXA)
Jets emerge from the vicinity of a black hole or neutron star, which orbits a massive regular star in the LS 5039 system. Some of the gamma rays produced in the system are transformed into particles of matter and antimatter through collisions with ultraviolet photons (Illustration: HESS Collaboration/R Hynes)
NASA's Mars Global Surveyor spacecraft has returned more data on Mars than all previous missions to the planet combined (Illustration: NASA/Corby Waste)
Matter can stably orbit closer to a spinning black hole, right, than a non-spinning one, left (Illustration: NASA/CXC/M Weiss)
NASA may call on its fleet of Martian probes – including the twin rovers – to come to the aid of its Mars Global Surveyor spacecraft, which has not called home in more than a week.
Some of the most distant galaxies ever seen appear in the Hubble Ultra Deep Field North, a portion of which is shown here. If a new servicing mission is approved, a new instrument called the Wide Field Camera 3 would spot galaxies even more distant, and therefore further back in time (Image: NASA/ESA/S Beckwith/HUDF team)
The star V838 Monocerotis brightened in a peculiar outburst in 2002. An expanding "light echo" illuminates dust surrounding the star, highlighting more distant regions as time goes on. This latest view from Hubble was taken on 9 September (Image: NASA/ESA/H Bond/STScI)
Much of Mars’s water may still be present in the form of buried ice - this region near the equator that may consist of jumbled blocks of ice beneath a shroud of dust (Image: ESA/DLR/F U Berlin/G Neukum)
The McMurdo panorama is the largest and most detailed image taken by either Mars rover to date. It shows the view from Spirit's spot in the Columbia Hills (Image: JPL/NASA)
The "Face on Mars" is revealed as a lumpy hill in this new view with a resolution of 13.7 metres per pixel. Mission scientists reconstructed the 3D shape of the hill using data from Mars Express's stereo camera and overlaid it with fine surface details from Mars Global Surveyor's Mars Orbiter Camera (Image: ESA/DLR/FU Berlin/G Neukum/MOC/MSSS)
The Solar-B spacecraft will probe the triggers of potentially hazardous ejections of gas from the Sun (Illustration: NASA)
A radar instrument that could spot liquid water under the Red Planet's surface is set to deploy on Saturday from NASA’s Mars Reconnaissance Orbiter (MRO). If all goes according to plan, it should be able to start peeking beneath the Martian surface by the end of September.
