Ancient Asteroid Destroyer Finally Found, And It's a New Kind of Meteorite

A strange meteorite from Sweden is a new kind of space rock never before seen on Earth, a study reports. The baseball-sized gray blob could be the long-sought "other half" of an asteroid belt collision 470 million years ago.

Eta Carinae: New View of Doomed Star


This composite image of Eta Carinae from NASA's Chandra X-ray Observatory and Hubble Space Telescope shows the remnants of a massive eruption from the star during the 1840s. The X-ray data (yellow) show where material from that explosion has collided with nearby gas and dust. The optical data (blue) reveals material ejected from the star has formed a bipolar structure. Chandra detects a faint X-ray reflection off the inner optical nebula due to the collision of stellar winds between Eta Carinae and a suspected companion star.

Illustration of Objects from Our Solar System

One star, eight planets, and a myriad of moons, comets, asteroids, and five dwarf planets (only Pluto shown). This is the Earth's local neighborhood known as the Solar System. Despite studying this system for centuries, astronomers still yearn to know much more. Chandra is providing new insight and uncovering new mysteries about objects of all sizes and across all distances throughout our Solar Sytem. (Planets not to scale).

Runaway Pulsar Firing an Extraordinary Jet

An extraordinary jet trailing behind a runaway pulsar is seen in this composite image that contains X-ray data from Chandra (purple), radio data from the ACTA (green), and optical data from the 2MASS survey (red, green, and blue). The pulsar - a spinning neutron star - and its tail are found in the lower right of this image. The tail stretches for 37 light years, making it the longest X-ray jet ever seen from an object in the Milky Way galaxy. The pulsar is moving away from the center of the supernova remnant (seen in the upper left of the image) where it was born at a speed between 2.5 million and 5 million miles per hour. This supersonic pace makes IGR J1104-6103 one of the fastest moving pulsars ever observed.

Getting a Full Picture of an Elusive Subject

Two teams of astronomers have used data from Chandra and other telescopes to map the distribution of dark matter in three dimensions in the galaxy cluster Abell 383. The dark matter in Abell 383 is stretched out like a gigantic football with the point of the football aligned close to the line of sight. The X-ray data (purple) from Chandra in the composite image show the hot gas, which is by far the dominant type of normal matter in the cluster. Galaxies are shown with the optical data from the Hubble, the Very Large Telescope, and the Sloan Digital Sky Survey, colored in blue and white.

Dos luces se mueven en el cielo esta noche

Curioso avistamiento de objetos en órbita.
Un inusual avistamiento de la Estación Espacial Internacional ocurre hoy viernes en la noche. La Sociedad de Astronomía del Caribe (SAC) informó que entre las 8:10 p.m. y 8:12 p.m. se podrá apreciar al laboratorio espacial apareciendo por el noroeste y luciendo como una brillante estrella moviéndose, pero esta vez tendrá compañía.

"No sólo se podrá ver a la Estación Espacial luciendo muy brillante esta noche, sino que además se podrá apreciar una segunda luz y aunque más tenue, lucirá moviéndose algo cerca de la plataforma espacial por lo que este avistamiento lucirá curioso", señaló la SAC.

La entidad educativa explicó que casualmente un tanque de un cohete ruso Protón que fue lanzado al espacio en el año 2003 estará pasando sobre el Caribe en momentos en que la Estación Espacial estaría también pasando sobre nuestra zona, por lo que ambos objetos serán visibles a simple vista de forma simultánea. Aunque el tanque "Breeze" lucirá mucho menos brillante que la Estación, este podrá ser apreciado con facilidad, especialmente desde lugares alejados del alumbrado.

(Avistamiento sólo desde el Caribe, entre 8:10 p.m. y 8:12 p.m.)
