  • Astronomers re-discover an ignored celestial gem

    06/10/2008 3:05:01 PM PDT · by LibWhacker · 1 replies · 394+ views
    ESA's orbiting X-ray observatory XMM-Newton has re-discovered an ignored celestial gem. The object in question is one of the youngest and brightest supernova remnants in the Milky Way, the corpse of a star that exploded around 1000 years ago. Its shape, age and chemical composition will allow astronomers to better understand the violent ways in which stars end their lives. Exploding stars seed the Universe with heavy chemical elements necessary to build planets and create life. The expanding cloud of debris that each explosion leaves behind, known as a supernova remnant (SNR), is a bright source of X-rays and radio...

    While peering at her computer screen four months ago, astronomer Alicia Soderberg expected to see the small glowing smudge of a month-old supernova. But what she and her colleague saw instead was a strange, extremely bright, five-minute burst of X-rays. With that observation, they became the first astronomers to catch a star in the act of exploding. "For years we have dreamed of seeing a star just as it was exploding, but actually finding one is a once-in-a-lifetime, event," said Soderberg, a Hubble and Carnegie Princeton Fellow at Princeton University. The discovery, detailed in the May 22 issue of the...

    NASA's Chandra X-ray Observatory and the National Radio Astronomy Observatory's Very Large Array have combined to discover the youngest supernova in the Milky Way galaxy. At only 140 years old the supernova is younger than Cassiopeia A, the last known supernova in our galaxy which occurred around 1680. It had been missed by optical telescopes on Earth because it occurred close to the center of the galaxy and is embedded in a dense field of gas and dust, making it a trillion times fainter according to a NASA statement.

    Thanks to a lucky break and an overactive galaxy, astronomers have for the first time caught a massive star in the act of exploding. An X-ray outburst recently recorded by NASA's Swift satellite suggests that researchers began viewing the violent demise of a star in the galaxy NGC 2770 just a few seconds after the first X rays arrived at Earth, and hours before the first visible-light fireworks. Most supernovas aren't identified until they generate an outpouring of visible light, long after key information about the size and other properties of the collapsing star has vanished. The new finding suggests...

    In a cascade of superlatives that belies the traditional cerebral reserve of their profession, astronomers reported Monday that they had seen the brightest and most powerful stellar explosion ever recorded. The cataclysm - a monster more than a hundred times as energetic as the typical supernova in which normal massive stars end their lives - may be an example, they said, of a completely new type of explosion. Such a blast, proposed but never seen, would explain how the earliest and most massive stars in the universe ended their lives and strewed new elements across space to fertilize future stars...

We know the masses and general composition of the four inner (rocky) planets in our solar system, and from basic chemistry, we know the number of atoms in a gram of any material. Multiplying Avogadro's number x the mass of these four planets, dividing by a weighted average atomic weight for the materials in each planet, we get about 3 x 10^ 50 heavy nuclei produced since creation/the big bang.

  • 'Pillars of Creation' Destroyed by Supernova

    The famous "pillars of creation" – clouds of dust and gas imaged by the Hubble Space Telescope, are no more – a supernova blast wave has blown them apart. But their ghostly image will linger for another thousand years because of the time it takes for light to travel from them to Earth. The pillars have been astronomical icons since Hubble imaged them in 1995 (scroll down for Hubble image). They are part of a larger star-forming region called the Eagle Nebula, which lies 7000 light years away. That means we are seeing the pillars as they were 7000 years...

    PARIS (AFP) - Astronomers in Europe and the United States have detected the remnants of two exploding stars that could lead to a rethink about supernovae, the European Space Agency said. The team examined X-ray data from the embers of two supernovae, DEM L238 and DEM L249, which were stars that had exploded in a nearby galaxy. Most supernovae occur when a very massive star runs out of fuel, its core collapses and then explodes, leaving behind a neutron star or a black hole. But there is also a rarer supernova, called Type 1a, which starts with a binary system...

    A new discovery is casting doubt on the idea that a type of star explosion shines with equal brightness wherever it occurs in the universe. The finding could have implications for estimates of the size of the cosmos. Type-1a supernovae are typically used as standard indicators of distance in the vast expanse of the universe. But the discovery of a Type-1a supernova more massive than was thought possible could force astronomers to rethink their ideas about the luminous objects, scientists reported today. ... It was thought that all Type-1a supernovae emit equal amounts of light at their peak and fade...

    A star in a galaxy about 440 million light-years away released in a few seconds more energy than the sun will over the course of its entire lifetime, according to observations made on February 18. A high-energy jet of x-rays shot out from the doomed star's core and was captured by the Burst Alert Telescope on NASA's Swift satellite. The satellite relayed the information to astronomers on the ground, and within days a wide array of telescopes turned to the exploding object. Meanwhile the other telescopes on Swift continued to observe the unusually long-lived burst; it lasted 40 minutes compared...

    LONDON (Reuters) - Teams of international scientists have used observations from NASA's Swift satellite and other telescopes to witness the evolution of a cosmic blast into a stellar explosion or supernova. The blast is thought to be a milder type of gamma-ray burst (GRB) -- the most powerful type of explosion known to astronomers -- called an X-ray flash. It is known as GRB060218 after the February 18 date it began in the constellation of Aries about 440 million light years away.

However, a closer 24.5-hour examination with the European Space Agency's XMM Newton X-ray satellite reveals that the energetic X-ray emissions of the blue, point-like object cycles every 6.7 hours-tens of thousands of times longer than expected...

    A search for the remains of a nearby stellar explosion has come up empty. Astronomers observed the blast site of the supernova, SN 1987A, with the Hubble Space Telescope, but could not find any sign of the dense stellar core. "We think a neutron star was formed. The question is: Why don't we see it?" astronomer Genevieve Graves of UC Santa Cruz said today. A neutron star is an extremely dense ball of subatomic particles, which theory says can form as the core of a massive star collapses after exploding. This is what is believed to have happened in 1987,...

    NASHVILLE -- Astronomers have peered through a secretive cloak of dust to find five exploded stars in a region of space believed to be among the most energetic in the universe. They're calling it a supernova factory, the first of its kind ever witnessed. The supernovae, forged at the intersection of two merging galaxies, help confirm a long-held theoretical expectation that galaxy collisions generate episodes of intense star birth and rapid death. Astronomers call these merging objects starbirth galaxies, and they are thought to be a primary driving force of cosmic evolution. The work represents an initial step toward a...
