Astronomers using ground and space telescopes around the world have revealed a black hole and a star, intertwined in a cosmic tango together.

Are We There Yet? Astronomers Measure Distance To Neighboring Galaxy
2013-03-06 12:13:52

Astronomers have now accurately measured the distance to our neighboring galaxy, the Large Magellanic Cloud after using observations of eclipsing binaries.

Scientists Recreate Spiral Arms Of Ancient Milky Way

A pair of French scientists has been able to recreate how the Milky Way’s spiral arms looked millions of years ago.

Astronomers Shed Light On Old Star Using New Greek Observatory
2013-02-27 08:44:17

Continuing a tradition stretching back more than 25 centuries, astronomers have used the new 2.3-m 'Aristarchos' telescope, sited at Helmos Observatory (2340m high) in the Pelοponnese Mountains in Greece, to determine the distance to and history of an enigmatic stellar system, discovering it to likely be a binary star cocooned within an exotic nebula.

Crowded Star Clusters Defy Simple View Of Gravity
2013-02-21 09:00:07

On large astronomical scales, gravity remains the dominant force acting on heavenly bodies. But when it comes to young clusters of stars, researchers say these crowded environments cannot be fully accounted for by a simple view of gravity.

Study Reveals Secrets Of Binary Stars Through Red Explosions
2013-01-25 11:12:34

Astrophysicists have debated the outcome of two binary stars – stars that orbit each other – coming together in a "common envelope" for a long time. A new study from the University of Alberta has finally provided some answers.

Binary Star Orbit Shifts Could Force Planetary Ejections
2013-01-07 03:28:35

The orbits of distant binary stars can become altered over time, potentially causing violent disruptions in their planetary systems and possibly causing worlds to become scattered or ejected, an international team of astrophysicists has discovered in a new study.

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...

X-ray Burster -- X-ray bursters are a class of binary stars which are luminous in X-rays. They contain a neutron star and a low-mass companion star. The companion fills its Roche lobe and therefore the neutron star is accreting matter from it. The inflowing gas forms an accretion disk around the neutron star. Sometimes X-ray bursters show a sudden increase in their X-ray luminosity, called X-ray burst. All properties of the X-ray bursts can be explained assuming that they result from...

X-ray Binaries -- X-ray binaries are a class of binary stars that are very luminous in X-rays. The X-rays are produced by matter falling from one component (usually a relatively normal star) to the other component, which is a neutron star or a black hole. The infalling matter releases gravitational potential energy, up to several tens of per cent of its rest mass as X-rays. (Hydrogen fusion releases about 0.7 per cent of rest mass) X-ray binaries are further subdivided into...

Variable Star -- Most stars are of nearly constant luminosity. Our own Sun is a good example which goes through practically no measurable variation in brightness. There are, however, stars which do vary in brightness, called variable stars. They fall into two main groups: Intrinsic variables These are stars which have intrinsic variations in brightness, that is the star itself gets brighter and dimmer. There are many types of intrinsic variables, the main types being: -- Mira...

Triple Star -- A triple star system consists of three gravitationally bound stars. The stars are in orbits around a common center of mass, usually so that two of the stars form a close binary star and the third is further away. This configuration is often called a hierarchical triple star. Multiple stars containing more than three stars can usually be decomposed to binaries and single stars that are in a hierachically bound system. ----- Click here to learn more on this...
