Galaxies Coming Of Age In Cosmic Blobs

This is the first of a pair of artist’s representations showing what one of the
galaxies inside a blob might look like if viewed at a relatively close distance.

The “coming of age” of galaxies and black holes has been pinpointed, thanks to new data from NASA’s Chandra X-ray Observatory and other telescopes. This discovery helps resolve the true nature of gigantic blobs of gas observed around very young galaxies.

New Light Shed On ‘Dark’ Gamma-ray Bursts

Dense knots of dust in otherwise normal galaxies dim the light of a dark gamma-ray burst

Gamma-ray bursts are the universe’s biggest explosions, capable of producing so much light that ground-based telescopes easily detect it billions of light-years away. Yet, for more than a decade, astronomers have puzzled over the nature of so-called dark bursts, which produce gamma rays and X-rays but little or no visible light. They make up roughly half of the bursts detected by NASA’s Swift satellite since its 2004 launch.

member of a select class of objects called magnetars.

NASA’s Swift satellite reported multiple blasts of radiation from a rare object known as a soft gamma repeater, or SGR. Now, astronomers report an in-depth study of these eruptions using the European Space Agency’s XMM-Newton and International Gamma-Ray Astrophysics Laboratory (INTEGRAL) satellites.

Extension For Earth Also Doubles Odds Of Finding Life On Other Planets

Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability

Roughly a billion years from now, the ever-increasing radiation from the sun will have heated Earth into inhabitability; the carbon dioxide in the atmosphere that serves as food for plant life will disappear, pulled out by the weathering of rocks; the oceans will evaporate; and all living things will disappear.

Birth Of A Star Predicted

The astrophysicist João Alves, director of the Calar Alto Observatory in Almeria, and his colleague Andreas Bürkert, from the German observatory in the University of Munich, believe that “the inevitable future of the starless cloud Barnard 68” is to collapse and give rise to a new star, according to an article which has been published recently in The Astrophysical Journal.

The Mysterious Mima Mounds

The Mysterious Mima Mounds 

We don’t know what they are, where they came from, or what caused them

Scientists love a mystery. Biologists used to have the human genome, but now they have the structure of protein. Physics used to have cosmic rays, but now they have the God particle. Astronomers used to have black holes, but now they have dark matter. (Pics)
