NASA Renames Observatory for Fermi, Reveals Entire Gamma-Ray Sky. NASA’s newest observatory, the Gamma-ray Large Area Space Telescope, or GLAST, has begun its mission of exploring the universe in high-energy gamma rays. The spacecraft and its revolutionary instruments passed their orbital checkout with flying colors. NASA announced today that GLAST has been renamed the Fermi Gamma-ray Space Telescope. The new name honors Prof. Enrico Fermi (1901 – 1954), a pioneer in high-energy physics. “Enrico Fermi was the first person to suggest how cosmic particles could be accelerated to high speeds,” said Paul Hertz, chief scientist for NASA’s Science Mission Directorate at NASA Headquarters in Washington. “His theory provides the foundation for understanding the new phenomena his namesake telescope will discover.” Scientists expect Fermi will discover many new pulsars in our own galaxy, reveal powerful processes near supermassive black holes at the cores of thousands of active galaxies and enable a search for signs of new physical laws. For two months following the spacecraft’s June 11 launch, scientists tested and calibrated its two instruments, the Large Area Telescope (LAT) and the GLAST Burst Monitor (GBM). The LAT team today unveiled …

Hubble’s Universe Unfiltered (1): Interacting Galaxies – Cosmic Collisions Galore. Hubble celebrated its 18th anniversary by releasing a huge image gallery of interacting galaxies. Such galaxies pass close enough to each other that their mutual gravity can stretch and distort their shapes. Eventually, interacting galaxies merge together to form a single larger galaxy. However, since these interactions can take billions of years, how do we study them? And how do we make sense of the variety of strange shapes seen in these Hubble images? — Subscribe to Science & Reason: • www.YouTube.com • www.YouTube.com — Astronomy textbooks typically present galaxies as staid, solitary, and majestic island worlds of glittering stars. But galaxies have a dynamical side. They have close encounters that sometimes end in grand mergers and overflowing sites of new star birth as the colliding galaxies morph into wondrous new shapes. In celebration of the Hubble Space Telescope’s 18th launch anniversary, 59 views of colliding galaxies constitute the largest collection of Hubble images ever released to the public. This new Hubble atlas dramatically illustrates how galaxy collisions produce a remarkable variety of intricate structures in never-before-seen detail. Notes: • Hubble was launched into orbit on April 24, 1990, aboard the space shuttle Discovery. However, there is a lot more to its history than just 18 years (so far) of cutting edge science. Take a look at Hubble Essentials for more …

This is an excerpt of a lecture given by Alexei V. Filippenko, Professor of Astronomy, for his class at UC Berkeley called “How Stars Shine: Cosmic Furnaces” (“Introduction General Astronomy”): • webcast.berkeley.edu Alex Filippenko’s research accomplishments, documented in about 500 published papers, have been recognized by several major prizes, and he is one of the world’s most highly cited astronomers. He has won the top teaching awards at Berkeley and has been voted the “Best Professor” on campus five times. In 2006, he was selected as the Carnegie/CASE Professor of the Year among doctoral institutions. He has produced three astronomy video courses with The Teaching Company and coauthored an award-winning textbook. He is an avid tennis player and hiker, enjoys world travel, and is addicted to experiencing total solar eclipses (8 and counting). • astro.berkeley.edu Thanks to RabidApe for inspiring me to make this video: www.youtube.com Subscribe to Science & Reason: • www.youtube.com • www.youtube.com • www.youtube.com ————————————————————— SPACE: Want to know why we don’t have to worry about our sun burning out?

SN 1987A was a supernova in the outskirts of the Tarantula Nebula in the Large Magellanic Cloud, a nearby dwarf galaxy. It occurred approximately 51.4 kiloparsecs from Earth,[1] close enough that it was visible to the naked eye. It could be seen from the Southern Hemisphere. It was the closest observed supernova since SN 1604, which occurred in the Milky Way itself. The light from the supernova reached Earth on February 23, 1987. As the first supernova discovered in 1987, it was labeled “1987A”. Its brightness peaked in May with an apparent magnitude of about 3 and slowly declined in the following months. It was the first opportunity for modern astronomers to see a supernova up close.

A supernova (pl. supernovae) is a stellar explosion. Supernovae are extremely luminous and cause a burst of radiation that often briefly outshines an entire galaxy, before fading from view over several weeks or months. During this short interval, a supernova can radiate as much energy as the Sun could emit over its entire life span.[1] The explosion expels much or all of a star’s material[2] at a velocity of up to 30000 km/s (a tenth the speed of light), driving a shock wave[3] into the surrounding interstellar medium. This shock wave sweeps up an expanding shell of gas and dust called a supernova remnant.
