![]() Short lifespans - only tens of thousands of years as a luminous blue variable - make these stars fairly rare scientists have only identified a few dozen in our Milky Way and nearby galaxies.Įmail Meghan Bartels at or follow her on Twitter Follow us on Twitter and on Facebook. AG Carinae, which scientists think is about 70 times more massive than the sun, may last perhaps 5 million or 6 million years. In the case of AG Carinae, that means outward pressure briefly overpowering gravity to spew material out into space, an outburst that stabilizes the star into balance again, more or less.īut even still, massive stars can only endure a certain number of such outbursts before running out of fuel. Within a star, the inward pressure of gravity and the outward pressure of radiation from the star typically balance, but in an unstable star, one occasionally wins out over the other. The outbursts, surprisingly, are a tactic to keep the star together, according to the ESA statement. ![]() (Image credit: ESA/Hubble, Digitized Sky Survey 2.

Elizabeth's reporting includes multiple exclusives with the White House and Office of the Vice-President of the United States, an exclusive conversation with aspiring space tourist (and NSYNC bassist) Lance Bass, speaking several times with the International Space Station, witnessing five human spaceflight launches on two continents, working inside a spacesuit, and participating in a simulated Mars mission.

From its vantage point high above Earth’s atmosphere, NASA’s Hubble Space Telescope has completed this years grand tour of the outer solar system returning crisp images that complement current and past observations from interplanetary spacecraft. This object is formally known as J025157.5+600606. The $10 billion telescope will be able to see the most distant and oldest galaxies and star clusters that formed in the first hundreds of millions of years after the Big Bang, enabling astronomers to answer fundamental questions about the evolution of the universe.įollow Elizabeth Howell on Twitter. This image, taken with the NASA/ESA Hubble Space Telescope, depicts a special class of star-forming nursery known as Free-floating Evaporating Gaseous Globules, or frEGGs for short. Webb, which should release its first science-grade images on July 12, is located much farther away from Earth than Hubble and has a much larger mirror. Knowing the true color of a star, along with its brightness, will better allow astronomers to estimate the age of individual stars of the globular cluster, ESA added.Īn even wider range of infrared capabilities will be available when NASA's James Webb Space Telescope comes online next month. It is a galaxy remarkable for its webs of shredded clouds and flame-like plumes of glowing hydrogen blasting out from its central regions where young stars are being born 10 times faster than they are inside in our Milky. ![]() Hubble telescope spots a complex cloud of gas expanding into space This mosaic image of the magnificent starburst galaxy, Messier 82 (M82) is the sharpest wide-angle view ever obtained of M82. ![]() These star-forming spirals look like galactic UFOs The Hubble Space Telescope and 30 years that transformed our view of the universe ![]()
