Beautiful picture of a supernova remnant, featured on APOD a couple of days ago. It’s located in the Small Magellanic Cloud, one of our Galaxy’s closest neighbours, at a distance of around 190,000 lightyears.

The image is a composite of X-ray and optical observations.

Today, the 4th of July, the Earth’s elliptical orbit takes our planet to its farthest point from the Sun (‘aphelion‘). This composite image demonstrates nicely how this causes the Sun to appear just a tad smaller in the sky compared with the perihelion size, at the closest approach.

In keeping with this week’s Launchtastic theme, today’s APOD is a beatiful picture of Space Shuttle Atlantis on the launch pad at Cape Canaveral. Atlantis is currently under way to rendez-vous with the Hubble Space Telescope to carry out essential repairs to ready the telescope for 5 more years of science operation.

Remember when the folks at NASA gave us all the opportunity to vote for a target to observe with the Hubble Space Telescope? (more…)

APOD: Some very fluffy-looking clouds February 5, 2009

This picture fits into my Venn diagram of “cool weather phenomena” and “the fluffy theme I’ve got going on today”. Stacked lenticular clouds these are called, acoording to APOD, and they occure near mountain tops where moist air is forced to flow upwards instead of spread horizontally. The mountain in question here is Mt Rainier in Washington, USA. More very cool pictures of lenticular clouds here.
