What's causing those odd rings in supernova 1987A? Twenty five years ago, in 1987, the brightest supernova in recent history was seen in the Large Magellanic Clouds. At the center of the above picture is an object central to the remains of the violentstellar explosion. Surrounding the center are curious outer rings appearing as a flattened figure 8. Although large telescopes including the Hubble Space Telescope monitor the curious rings every few years     The Mysterious ... Full Story

The Case of the Missing Supernova Companion, Where's the other star? At the center of this supernova remnant should be the companion star to the star that blew up. Identifying this star is important for understanding just how Type Ia supernova detonate, which in turn could lead to a better understanding of why the brightness of such explosions are so predictable, which in turn is key to calibrating the entire nature of our universe. The trouble is that even a careful inspection of the center of ... Full Story

Few butterflies have a wingspan this big. The bright clusters and nebulae of planet Earth's night sky are often named for flowers or insects, and NGC 6302 is no exception. With an estimated surface temperature of about 250,000 degrees C, the central star of this particular planetary nebula is exceptionally hot though -The Butterfly Nebula from Hubble  Image Credit: NASA, ESA, and the Hubble SM4 ERO Team Explanation: Few butterflies have a wingspan this big.

The GRB 110328A Symphony Credit: NASA, ESA, and A. Fruchter (STScI) Explanation: A symphony of planet-wide observations began abruptly on March 28 when the Earth-orbiting Swift satellite detected a burst of high-frequency gamma-rays from GRB 110328A. When the same source flared again after a45 minute pause it was clear this event was not a typical gamma-ray burst. Twelve hours after the initial fanfare astronomers using the 2.5-meter Nordic Optical Telescope chimed in with a ... Full Story

  NGC 4449: Close-up of a Small Galaxy Credit: Data - Hubble Legacy Archive, ESA, NASA; Processing - Robert Gendler   Explanation: Grand spiral galaxies often seem to get all the glory. Their young, blue star clusters and pink star forming regions along sweeping spiral arms are guaranteed to attract attention. But small irregular galaxies form stars too, likeNGC 4449, about 12 million light-years distant. Less than 20,000 light-years across, the small island ... Full Story
