By observing a high-speed component of a massive galaxy cluster, Caltech/JPL scientists and collaborators have detected for the first time in an individual object the kinetic Sunyaev-Zel'dovich effect, a change in the cosmic microwave background caused by its interaction with massive moving objects.
This new Hubble image shows the spiral galaxy Messier 83, otherwise known as the Southern Pinwheel Galaxy. One of the largest and closest barred spirals to us, this galaxy is dramatic and mysterious; it has hosted a large number of supernova explosions, and is thought to have a double nucleus lurking at its core.
Located some 25 million light-years away, this new Hubble image shows spiral galaxy ESO 373-8. Together with at least seven of its galactic neighbors, this galaxy is a member of the NGC 2997 group. We see it side-on as a thin, glittering streak across the sky, with all its contents neatly aligned in the same plane.
The Galaxy has been making stars for the last 8 billion years. What’s kept it going all that time? When old stars die, some of their gas goes back into the galactic “soup” for star making. But in the long run a lot of it gets locked up in long-lived dwarf stars.
How many rings do you see in this new image of the galaxy Messier 94 (below), also known as NGC 4736? While at first glance one might see a number of them, astronomers believe there is just one. This particular image was captured in infrared light by NASA's Spitzer Space Telescope.
A giant black hole in the center of the galaxy 4C+29.30 is generating two powerful jets of particles.
Worldwide tablet sales continued to surge, growing 142.4 percent in the first quarter of 2013.
Astronomers have discovered a galaxy transforming gas into stars with almost 100 percent efficiency - a rare phase of galaxy evolution that is the most extreme yet observed.
Samsung posted its financial estimations in the three months to the end of March, with enormous expected operating profits of roughly $7.7 billion (8.7 trillion won) - up over 50 percent from the same time last year.
Samsung is reportedly prepping a new mobile device dubbed the Altius.
Astronomers have made the most precise measurement ever of how the universe has cooled down during its 13.77 billion year history - putting the Big Bang theory to the test.
Samsung's Galaxy Note devices are currently available in two primary sizes - 5.5-inches (smartphone form factor) and 10.1-inches (tablet).
Astronomers have discovered enormous outflows of charged particles from the centre of our galaxy, moving at supersonic speeds.
Astronomers have classified a new type of galaxy after they noticed that it glowed an unusually bright green.
NASA astronomers describe NGC 3344 as a "glorious" spiral galaxy around half the size of the Milky Way, which lies some 25 million light-years distant.
Apple's lost its appeal over a UK ruling that Samsung's Galaxy tablet doesn't infringe its registered design for the iPad - a decision that is valid in the whole of Europe.
The US Court of Appeals has overturned the ban on sales of Samsung's Galaxy Nexus phone, saying the California court that imposed it had 'abused its discretion'.
Samsung has reported a quarterly profit of $7.3 billion - nearly double the figure for the same period last year, and well above analysts' expectations - thanks to strong sales of high end televisions and Galaxy phones.
Samsung has responded to the news that created shock waves yesterday.
Our Milky Way Galaxy is surrounded by an enormous halo of hot gas hundreds of thousands of light years across, and with as much mass as all the stars in the galaxy.
