Latest Alpha Centauri Stories
Astronomers have discovered a planet similar in mass to the Earth orbiting a star in the Alpha Centauri system — the nearest to Earth. Surpisingly, according to the astronomers, this planet which is just 4 light years away is also the lightest ever discovered around a star like our Sun.

With some inspiration from the studies of ocean life forms, a British space expert envisages alien lifeforms that resemble jellyfish with organs developed to ingest methane and other chemicals for its nutrition, keeping aloft by means of dangling onion-like buoyancy bags, and communicating with pulses of light.
Just as some drivers obey the speed limit while others treat every road as if it were the Autobahn, some stars move through space faster than others.
Just like out of a good science fiction setting on some far-off planet, our own Earth could soon have a second sun, but only for a limited time.
Astronomers are used to looking millions of years into the past, and now scientists have used the Hubble Space Telescope to look thousands of years into the future.
Twentieth Century Fox makes history by transmitting the first motion picture in to deep space, making THE DAY THE EARTH STOOD STILL the worldâ€™s first galactic motion picture release.
Omega Centauri is one of the finest jewels of the southern hemisphere night sky, as ESO's latest stunning image beautifully illustrates.
A rocky planet similar to Earth may be orbiting one of our nearest stellar neighbors and could be detected using existing techniques, according to a new study led by astronomers at the University of California, Santa Cruz.
Lyra Constellation -- Lyra (the lyre) is a prominent, although fairly small, northern constellation. It was one of Ptolemy's 48 constellations, and also counts among the modern 88 constellations. Its brightest star is Vega (Alpha Lyrae), which together with Altair (Alpha Aquilae) and Deneb (Alpha Cygni) forms the large asterism known as the Summer Triangle. Beta Lyr is a half separated (i.e. one of the stars reached its Rochevolume) eclipsing binary of a cream-white colour. The...
Centaurus Constellation -- Centaurus (the centaur) was one of the 48 constellations listed by Ptolemy, and counts also among the 88 modern constellations. A constellation of the southern hemisphere, mentioned by Eudoxus (4th century B.C.) and Aratus (3rd century B.C.), Ptolemy catalogued thirty-seven stars in it. It contains Proxima Centauri, the red dwarf that is the nearest known star (other than the Sun) to Earth, as well as Alpha Centauri, which is a double star to which Proxima...
Red Dwarf -- A red dwarf is a small star on the main sequence, either late K or M spectral type. They have a diameter and mass of less than one-third that of the Sun (down to 0.08 solar masses, which are Brown dwarves) and a surface temperature of less than 3,500 K. They emit little light, sometimes as little as 1/10,000th that of the sun. Due to the slow rate at which they burn hydrogen red dwarves have a enormous lifespan, estimates range from a tens of billions up to trillions of...
Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....
Proxima Centauri -- The red dwarf star Proxima Centauri (also Alpha Centauri C), part of the Alpha Centauri star system, is the nearest star to our Earth other than the Sun. Proxima Centauri is roughly 4.22 light years from Earth, 270,000 times as far as the sun. Its apparent magnitude is 11 (very weak, as red dwarfs in general are: far too weak to be observable with the naked eye). Proxima Centauri has often been suggested as a logical first destination for interstellar travel....
