Bring on the Mayan doomsday predictions.  NASA’s SDO (Solar Dynamics Observatory) captured this M-class solar flare on March 13, at 1:29 p.m. EDT.   Solar flares are classed in three categories: X- M- and C-, and solar flares are the strongest explosive event in our solar system, so this was a medium.  Incidentally, the teal color is normal for the Angstrom wavelength being shown in this image.  The magnetic energy put out by an M-class flare can cause brief radio blackouts that affect the Earth’s polar regions.

This image of the Large Magellanic Cloud (dwarf satellite galaxy of the Milky Way) was taken by the NASA/ESA Hubble Space Telescope’s Wide Field Planetary Camera 2.  This loose star cluster — known as a stellar grouping — is classified as an OB association.  OB’s usually contain 10-100 high mass stars with brilliant but short lives.  Speculations is that most of the Milky Way’s stars were created in OB associations.

Eye on the Sky: UFO Galaxy

Captured in visible and infrared light by Hubble’s Advanced Camera for Surveys, the UFO Galaxy image (NGC 2683) is a side-on view, giving the galaxy it’s distinctive nickname.  It looks like the classic sci-fi image of an alien ship.  UFO is, like our own, a spiral galaxy, and this view of it allows astronomers to see details like dusty space lanes and clusters of young blue stars in the galaxy’s star-forming regions.

Eye on the Sky: Cygnus Loop Nebula

Ultra violet image taken by NASA’s Galaxy Evolution Explorer.  The Cygnus Loop Nebula is a leftover supernova remnant of the massive explosion that occurred 5,000-8,000 years ago.  What you are seeing is gas and dust heated by the shockwave of the supernova that is still spreading outward from the explosion.  Although the nebula is 1,500 light years away, the supernova was still bright enough to be seen from Earth when it exploded.

Eye on the Sky: Supernova Preview

Hubble Telescope image of Eta Carinae in ultraviolet and visible light taken by the High Resolution Channel Advanced Camera for Surveys.
This is what’s known as a supernova imposter event because it appears similar but the star hasn’t actually been destroyed.  The Eta Carinae systen is one of the closest to Earth so expect the supernova to be very bright when it does happen.  But since we’re talking about events in a galactic time frame, you probably won’t be alive to see it.

Eye on the Sky: 30 Doradus Nebula

30 Doradus nebula is a star birth region in the Large Magellanic Cloud.  The image was taken by Hubble’s Wide Field Camera 3 in ultraviolet, visible and red light, and this grouping alone spans 100 light years.  Several of these beautiful ice blue stars, at 100 times more massive than our sun, are among the largest known stars.
