Feb. 28  More evidence in favour of MOND?
Modified Newtonian dynamics (MOND) is the name given to a theory proposed in 1983 by the physicist Mordehai Milgrom, to get over some of the apparent shortcomings shown by Newtonian gravity when >>>
Feb. 25  Asteroids: Kleopatra and her twins
In this month's issue of the journal Icarus, the results of a long study of asteroid 216 Kleopatra, and other large asteroids with small satellites, are published. The main authors of the study are >>>
Feb. 24  A family portrait of the solar system
Using the Wide Angle Camera (WAC) and the Narrow Angle Camera (NAC) of the Mercury Dual Imaging System (MDIS) on-board NASA's MESSENGER probe (MErcury Surface, Space, ENvironment >>>
Feb. 23  Lunar water full of metals and sodium
The results from the analysis of volatile material released by the LCROSS probe, that impacted in the crater Cabeus near the lunar pole on 9th October 2 years ago, have been confirmed (the cloud >>>
Feb. 22  Could rogue planets support life?
Do you remember the TV series "Space: 1999"? An enormous explosion of nuclear waste on the Moon pushes our satellite out of its orbit, marking the start of a long cosmic odyssey for the >>>
Feb. 21  Precision distance measurements with VLBA
We're all used to hearing about the superb angular resolution of space telescopes and the largest ground-based instruments, but only rather infrequently are we reminded that there is an instrument capable >>>
Feb. 18  The first image of the magnetosphere
Two single pixel cameras, using revolutionary technology, have been used to give "live" images of a large portion of the Earth's magnetosphere. The magnetosphere is the result of the >>>
Feb. 17  How much dark matter to make a galaxy?
Thanks to the Herschel Space Observatory, it has been possible to determine how much dark matter must be present at the time of formation of a galaxy, so that it can contract to form stars and >>>
Feb. 16  Stardust-NExT, mission accomplished!
Here are the first dramatic images of comet Tempel 1, just released by NASA, after the close flyby of the Stardust-NExT probe. These images were much anticipated as they provide, for the first time, the >>>
Feb. 15  Isolating the thick disk of M31
The results of a study, carried out by a group of Anglo-American researchers led by Michelle Collins (Cambridge's Institute of Astronomy), have been published in the Monthly Notices of the >>>
Feb. 14  Spitzer opens up the North America nebula
New images of the North America and Pelican nebula, obtained with the infrared sensors of the Spitzer space telescope, show these spectacular structures in a completely new light. What is seen at the infrared >>>
Feb. 11  A ring of stars and black holes in Arp 147
The Space Telescope Science Institute (STScI) in Baltimore has released this remarkable image of a cosmic ring, a fitting pre-Valentine's day image. The cause of this odd structure, 430 light >>>
Feb. 10  Stardust-NExT meets Tempel 1
There are 4 days and 3.8 million kilometers between the Stardust-NExT probe and its encounter with comet Temple 1. Both are veterans of previous historic encounters. Stardust, launched on 17th >>>
Feb. 9  Evidence for Martian water from Nakhlites
The results of the analysis of meteorite samples, carried out by John Bridges and Hitesh Changela (University of Leicester, Department of Physics and Astronomy) that show how asteroid impacts on Mars >>>
Feb. 8  Are there primordial stars that still shine?
Using very high resolution computer simulations, it has been shown that stars born in the primordial Universe from the gravitational contraction of gigantic gas clouds that formed after the Big Bang, may still >>>
Feb. 7  From the other side of the Sun
For the first time Man has been able to (almost) simultaneously observe the entire solar surface. This has been made possible by the twin probes of STEREO (Solar TErrestrial Relations Observatory) >>>
Feb. 4  A disrupted galaxy right next to Earth
At a distance of between 16,000 and 32,000 light years from the Earth there is a galaxy; or, to be more precise, a stellar stream, whose dynamics show that it represents the remnants of a dwarf galaxy >>>
Feb. 3  Important discoveries from Kepler data
Five Earth-sized planets, in orbit in the habitable zone around five different stars, smaller and cooler than the Sun, and a planetary system with 6 transiting planets. These are the most >>>
Feb. 2  All the WISE comets, and more...
Tens of thousands of asteroids and 20 new comets are the result of the recently completed NEOWISE mission, that has spent 4 months searching for minor bodies in our solar system. When, at the >>>
