Picture of the Day: Monster Saturn Storm

Cassini has been circling Saturn for years, but it’s still revealing spectacular things about the planet. Violent weather provides a great spectacle on Earth, as long as it doesn’t actually destroy anything, but it’s nothing compared with what’s happening on Saturn.

Picture of the Day: The North-American nebula

Here’s a truly gorgeous image by astrophotographer Mick Hyde, a mosaic of NGC 7000 (the North American nebula) and the Pelican nebula (IC 5070). The structure on the upper left side is the North American nebula, with the darkest lobe of dust near the center forming the “Gulf of Mexico.” The star-forming region is located […]

Picture of the Day: Fairy Circles

Picture of the Day: Colliding binary star winds

An artist’s rendering of a colliding wind binary.     A colliding-wind binary is a binary star system in which the two members are massive stars that emit powerful, radiatively-driven stellar winds. The location where these two winds collide produces a strong shock front that can cause radio, X-ray and possibly synchrotron radiation emission. Wind […]

Picture of the Day: Orion

  Humans have been gazing at Orion for millennia, but they’ve never seen it as beautiful as this. Granted, we can’t actually see it like the photo above would suggest, as the fiery glow is only visible to telescopes tuned to submillimeter radio frequencies.

Picture of the Day: Venus

Artist’s impression of an active volcano on Venus. Results from a long-term study of Venus find evidence of a clear injection of sulphur dioxide into its upper atmosphere. One possible interpretation is that volcanic activity increased the sulphur dioxide component of the upper atmosphere, although an alternative is that a change in atmospheric circulation dredged […]

Picture of the Day: Algae Bloom

The stunning picture above shows several phytoplankton blooms as seen from space, and was made available to the public by the NASA Earth Observatory.

Picture of the Day: Milk, up close

Micro-particles of lactose (milk particles) are traped in self-organized structures made from the thin film metal. The scale bar represents 4 micrometers.

Picture of the Day: It dawns at the Moon

During his evening ritual of sharing images taken from the International Space Station, Commander Chris Hadfield posted this gem: a gorgeous night-time view of the southeastern United States, with the Moon hovering over Earth’s limb and the terminator separating night from day. Dawn is just beginning to break to the east, as the ISS flies […]
