Shrinking giants, exploding dwarves
When white dwarf stars explode, they leave behind a rapidly expanding cloud of 'stardust' known as a Type Ia supernova. These exploding events, which shine billions of times brighter than our sun, are all presumed to be extremely similar, and thus have been used extensively as cosmological reference beacons to trace distance and the evolution of the Universe.

First view of a newborn millisecond pulsar?
Combining Hubble Space Telescope images with radio observations has revealed a highly unusual system consisting of a fast spinning pulsar and a bloated red companion star. The existence of the system is something of a mystery - the best explanation so far is that we have our first view of a millisecond pulsar just after it has been `spun up` by its red companion star.

NN Serpentis Artist's impression: image owned by University of Warwick - image created by Mark A. GarlickAstronomers at the University of Warwick and the University of Sheffield have helped discover an unusual star system which looks like, and may even once have behaved like, a game of snooker.

Cosmic dance helps galaxies lose weight
A study published this week in the journal Nature offers an explanation for the origin of dwarf spheroidal galaxies. The research may settle an outstanding puzzle in understanding galaxy formation. View More (2009-07-30)
Astronomers find extreme weather on an alien world
A University of Toronto-led team of astronomers has observed extreme brightness changes on a nearby brown dwarf that may indicate a storm grander than any seen yet on a planet. View More (2011-09-13)
Forming super-Earths by ultraviolet stripping
A new explanation for forming "super-Earths" suggests that they are more likely to be found orbiting red dwarf stars—the most abundant type of star—than gas giant planets like Jupiter and Saturn. View More (2006-06-08)
Unveiling the Secret of a Virgo Dwarf Galaxy
Dwarf galaxies may not be as impressive in appearance as their larger brethren, but they are at least as interestingfrom a scientific point of view. And sometimes they may have hidden properties that will only be found by means of careful observations, probing the signals of their stars at the faintest level. Such as the entirely unexpected, well developed spiral structure within an otherwise... View More (2000-05-03)
A Vanishing Star Revisited
Reinhold H'¤fner of the Munich University Observatory (Germany) is a happy astronomer. View More (1999-07-20)
Feuding helium dwarfs exposed by eclipse
Researchers at the University of Warwick have found a unique feuding double white dwarf star system where each star appears to have been stripped down to just its helium. View More (2011-05-25)
It may not be long before we see other worlds
WE MAY actually see a planet around a nearby star within the next six months. A team of British astronomers hope to achieve this feat by focusing their search on white dwarfs-dimly glowing stars at the end of their lives. Although more than 80 planets outside our Solar System have been discovered, all were detected indirectly, by observing the... View More (2002-03-06)
Future Evidence for Extraterrestrial Life Might Come from Dying Stars
Even dying stars could host planets with life - and if such life exists, we might be able to detect it within the next decade. View More (2013-02-26)
Explosive Stars with Good Table Manners
An exploding star known as a Type Ia supernova plays a key role in our understanding of the universe. View More (2012-03-21)
Caltech: Astronomers find ice and possibly methane on Snow White, a distant dwarf planet
stronomers at the California Institute of Technology (Caltech) have discovered that the dwarf planet 2007 OR10-nicknamed Snow White-is an icy world, with about half its surface covered in water ice that once flowed from ancient, slush-spewing volcanoes. View More (2011-08-23)
A ghostly green bubble
Stars the size of the Sun end their lives as tiny and faint white dwarf stars. View More (2013-04-10)
UBC astronomers discover how white dwarf stars get their 'kicks'
University of British Columbia astronomer Harvey Richer and UBC graduate student Saul Davis have discovered that white dwarf stars are born with a natal kick, explaining why these smoldering embers of Sun-like stars are found on the edge rather than at the centre of globular star clusters.

Astronomers discover new kind of supernova
Supernovae were always thought to occur in two main varieties. But a team of astronomers including Carnegie's Wendy Freedman, Mark Phillips and Eric Persson is reporting the discovery of a new type of supernova called Type Iax. View More (2013-03-27)
Many billions of rocky planets in the habitable zones around red dwarfs in the Milky Way
This first direct estimate of the number of light planets around red dwarf stars has just been announced by an international team using observations with the HARPS spectrograph on the 3.6-metre telescope at ESO's La Silla Observatory in Chile. View More (2012-03-28)
Galaxy NGC 4214: A star formation laboratory
Size isn't everything... in astronomy, at least. Dwarf galaxy NGC 4214 may be small, but what it lacks in size it makes up for in content. View More (2011-05-12)
Red kiwi poised to make a healthy debut
First there was green, then yellow and now red-fleshed kiwifruit. A team of researchers in Italy and New Zealand has found that a newly developed variety of red-fleshed kiwifruit contain anthocyanins, bright red pigments that are highly potent antioxidants. View More (2005-11-10)
New 'alien' invaders found in the Milky Way: Queen's University astronomer
As many as one quarter of the star clusters in our Milky Way - many more than previously thought - are invaders from other galaxies, according to a new study. View More (2010-03-01)
