A galaxy about 13.3 billion light-years away (inset in this image of a galaxy cluster from the Hubble Space Telescope and the Atacama Large Millimeter/submillimeter Array) is the most distant galaxy to show signs of rotation. ====================================================================== There is a galaxy spinning like a record in the early universe — far earlier than any others have been seen twirling around. Astronomers have spotted signs of rotation in the galaxy MACS1149-JD1, JD1 for short, which sits so far away that its light takes 13.3 billion years to reach Earth. “The galaxy we analyzed, JD1, is the most distant example of a...

Comet C/2017 K2 will be at its closest point to us for the next few million years this week. Hubble caught sight of comet K2 when it was out between the orbits of Saturn and Uranus. NASA, ESA, and A. Feild (STScI) One of the largest comets known is about to zip by our planet on the only trip through the inner solar system it will make during our lifetimes. Five years ago, the Hubble Space Telescope spotted a large comet at the farthest distance ever, as it was approaching the sun from way out between the orbits of Saturn...

NASA explains: In this NASA Hubble Space Telescope image taken on October 9, the comet’s solid nucleus is unresolved because it is so small. If the nucleus broke apart then Hubble would have likely seen evidence for multiple fragments. Moreover, the coma or head surrounding the comet’s nucleus is symmetric and smooth. This would probably not be the case if clusters of smaller fragments were flying along. What’s more, a polar jet of dust first seen in Hubble images taken in April is no longer visible and may have turned off. So, its not disintegrating, its not a three-piece body,...

NASA's next-generation space observatory promises to open new windows on the Universe — but its cost could close many more.It has to work — for astronomers, there is no plan B. NASA's James Webb Space Telescope (JWST), scheduled to launch in 2014, is the successor to the Hubble Space Telescope and the key to almost every big question that astronomers hope to answer in the coming decades. Its promised ability to peer back through space and time to the formation of the first galaxies made it the top priority in the 2001 astronomy and astrophysics decadal survey, one of a...

Worst-ever orbital collision leads to calls for tighter regulation.A cloud of debris spreading through low Earth orbit following the collision of two satellites poses a new risk to many scientific missions and may signal the demise of the Hubble Space Telescope. NASA is monitoring the increased threat carefully, and if it is as bad as some fear, the agency may have to cancel the proposed shuttle-servicing mission slated for later this year. Without that mission, the telescope's days are numbered, even if none of the new debris comes anywhere close to it.At 04:56 GMT on 10 February an active communications...

A tangle of spidery filaments stretches outward from the giant elliptical galaxy NGC 1275 as if they were dendrites of an intergalactic nerve cell. NGC 1275, located 235 million light-years from Earth near the center of a clump of galaxies known as the Perseus cluster, has posed a puzzle: How have these filaments, which are made of gas much cooler than the surrounding intergalactic cloud, persisted for perhaps 100 million years? Why haven’t they warmed, dissipated or collapsed to form stars? Images taken by the Hubble Space Telescope, with 10 times the resolution of earlier photographs, reveal that the filaments,...

The Hubble Space Telescope has a new, resonant date with destiny. NASA has set Sept. 11, 2008, as the target date for launching a mission intended to revitalize the telescope and keep it spaceworthy into the next decade, according to a planning document made public by nasawatch.com, an independent Web site. Three years ago, Sean O’Keefe, then the NASA administrator, decided to forgo Hubble telescope maintenance in the wake of the shuttle Columbia disaster, prompting a nationwide debate about the risks of shuttle flights and the value of the telescope. Michael D. Griffin, the current NASA administrator, reversed Mr. O’Keefe’s...

Astronomers said yesterday that they, or at least their telescopes, had laid eyes for the first time on planets beyond the solar system. Using the NASA Spitzer Space Telescope and careful timing, two different teams studying two different planets were able to distinguish the glow of the planets' infrared radiation from the overwhelming glare of their parent stars. Both planets are so-called hot Jupiters, massive bodies circling their stars in tight, blowtorching orbits and probably unfit for the kind of life found on Earth. Until now, astronomers could infer the existence and some properties of these and other so-called exoplanets...

SAN DIEGO -- Astronomers are highly confident that they've taken the first photograph of a planet outside our solar system. Make that two photographs. A new image from the Hubble Space Telescope confirms with a high degree of confidence a picture made previously by astronomers at the European Southern Observatory (ESO) and reported by SPACE.com in September. The planet -- still just a candidate, actually -- is an odd duck in many respects. It does not orbit a normal star, and it is much more massive than the largest planets in our solar system. Still, if confirmed, it represents a...
