  • The galaxy NGC 1277 in the Perseus cluster. Copyright: Sloan Digital Sky Survey (SDSS).
    The nearby galaxy NGC 1277 was formed at an early epoch of the cosmos and has remainedunchanged since then, thus making it a unique window on to the early Universe. Astronomers have found that the rate of star formation in massive galaxies at that remote epoch was much higher than expected with a thousand times more stars being generated than at present in the Milky Way.

  • Image of the comet ISON (the bright object in the upper part of the image) post-perihelion. The image was captured by the Solar Space Telescope (SOHO, NASA-ESA), at 12.30 UT on the 29th November 2013.
    ISON: Are you there? What remains of a comet post-perihelion? Earth based observations can tell us whether it still has its nucleus. ISON could be 'alive'. It is difficult to determine its current condition, so we do not know whether it is now just a tail or whether anything remains of its nucleus. The only images available are from solar space telescopes (particularly SOHO, see photograph), and they are at insufficient resolution to show the bright condensation at its centre where the nucleus of a comet normally resides. The data available confirms that ISON is alive but tells us nothing

    ISON has put itself at risk… The IAC accompanies ISON in his appointment with the Sun on November 28th. The IAC has obtained the latest images before perihelion, of a comet who is torn between life and death… From the skies of Canary Islands, the comet C/2012 S1 (ISON), is observed without atmospheric interference. The celestial body is on display these days, revealing all his activity. Comets are objects that have survived the formation of the giant planets and their satellites, the remains of the "bricks" with which they formed. These are real relics of the formation of the solar system

    Thanks to the Gran Telescopio CANARIAS (GTC), the authors have demonstrated that two companion stars orbiting black holes are indeed falling onto these black holes, but the spiral-in of these companion stars is faster than what the theory predicts.
