Galactic Pair: Porpoise or Penguin?

March 24, 2015 2:16 pm | by ESA | News | Comments

What do you see in this image: a porpoise or a penguin? Amateur astronomers have nicknamed this pretty galactic pair after both of these creatures — the graceful curve of a dolphin or porpoise can be seen in the blue- and red-tinged shape towards the bottom of the frame, and when paired with the pale, glowing orb just beneath it, the duo bear a striking resemblance to a bird or penguin guarding an egg.

Discovered on September 5, 1784, by astronomer William Herschel, the Veil Nebula was once a star. Now, it is a twisted mass of shock waves that appears six times larger than the full Moon in the sky. This Hubble Space Telescope image shows just a small part of the nebula, a region known as the ‘south-eastern knot.’ The entire nebula is about 50 light years in radius, and is located almost 1500 light years away.

Solar Dynamics: Curly-Q Filament Blast

February 19, 2015 11:04 am | by NASA | News | Comments

A solar filament erupted from the sun in the shape of a twisted arch, and the activity in the lower corona was caught in a wavelength of extreme ultraviolet light. The event occurred over a three-hour period on February 4, 2015, with most of the filament falling back into the Sun. Filaments are notoriously unstable.
