    An international team of scientists, including astronomers from the Universities of Leicester, Bath and Warwick, have found evidence for the existence of a 'hot cocoon' of material enveloping a relativistic jet escaping a dying star. This research is been published online today and in print in Nature tomorrow. [...]

    An image from the international Cassini spacecraft provides evidence of rainfall on the north pole of Titan, the largest of Saturn's moons. The rainfall would be the first indication of the start of a summer season in the moon's northern hemisphere. [...]

    Using Major Atmospheric Gamma-ray Imaging Cherenkov (MAGIC) telescopes, an international group of astronomers has detected a fast, very high-energy (VHE) flare from the blazar BL Lacertae. The finding is detailed in a paper published January 7 on the arXiv pre-print repository. [...]

    Humankind may be able to reach further back into the history of its nearest planetary neighbour, unlocking the secrets to the evolution, climate, and habitability of Mars, thanks to the efforts of a Western-led team tapped to improve NASA's rover technology. [...]

    In recent years, the number of extra-solar planets discovered around nearby M-type (red dwarf stars) has grown considerably. In many cases, these confirmed planets have been "Earth-like," meaning that they are terrestrial (aka. rocky) and comparable in size to Earth. These finds have been especially exciting since red dwarf stars are the most common in the universe – accounting for 85 percent of stars in the Milky Way alone. [...]

    A team of scientists has, for the first time, used a single, cohesive computer model to simulate the entire life cycle of a solar flare: from the buildup of energy thousands of kilometers below the solar surface, to the emergence of tangled magnetic field lines, to the explosive release of energy in a brilliant flash. [...]

    On Jan. 2, the New Horizons spacecraft made the most distant flyby ever attempted, successfully returning images of the Kuiper Belt object Ultima Thule. While the world is agog at the so-called "snowman" shape of this icy asteroid, the concept is nothing new to PSI scientist and artist, Bill Hartmann. The figure shows paintings that Hartmann made from 1978 to 1996, to illustrate the possible outcome of very low-velocity collisions of distant asteroids. These are compared with the first released color image of Ultima Thule. The story goes back 50 years. [...]

    New research led by an astronomer at the University of Warwick has found the first confirmed example of a double star system that has flipped its surrounding disc to a position that leaps over the orbital plane of those stars. The international team of astronomers used the Atacama Large Millimeter/sub-millimeter Array (ALMA) to obtain high-resolution images of the Asteroid belt-sized disc. [...]
