More Venus transits in 2012

Jay Pasachoff • June 07, 2012 • 3

A transit of Venus as seen from Jupiter may be observed by Hubble on September 20 and a transit of Venus as seen from Saturn will be observed by Cassini on December 21.

NRO gives NASA two hand-me-down telescopes

Jason Davis • June 07, 2012 • 4

The National Reconnaissance Office has donated two, partially-completed space telescopes to NASA, revealed at a National Academies' Committee on Astronomy and Astrophysics meeting this week.

Artist's views of a night sky transformed by a galaxy merger

Emily Lakdawalla • June 04, 2012 • 2

A measurement of the Andromeda galaxy's proper motion shows it's coming directly at us, and will collide with the Milky Way in 4 billion years. The event will transform the appearance of our night sky.

Hey amateurs! ESA's running an image processing contest: "Hubble's Hidden Treasures!"

Emily Lakdawalla • March 27, 2012

Here's a newly announced contest that is right up my alley and, I hope, of interest to regular readers of this blog. ESA has just announced "Hubble's Hidden Treasures," a contest to encourage what I've been trying to get people to do for years: trawl through the Hubble archives to find unappreciated tresures of photos and make them pretty for public consumption. They have two categories, one for newbies (who can use image processing tools provided on ESA's website) and one for more serious amateurs (who can use other software).

Looking down on a shooting star

Emily Lakdawalla • August 15, 2011

This photo is making the rounds of Twitter, Facebook, Google+, and whatever other social network you care to name today. It was shot by astronaut Ron Garan from the Space Station, and it's a meteor seen from above. Way cool.

A fourth moon for Pluto

Emily Lakdawalla • July 20, 2011 • 2

That's right: Hubble observations have yielded the discovery of a third small body orbiting Pluto and Charon.

Hubble's Millionth Observation

Bill Nye • July 05, 2011

The Hubble Space Telescope has recorded its millionth observation. The planet is designated HAT-P-7b.

The scale of our solar system

Emily Lakdawalla • May 02, 2011

Space.com has taken advantage of the infinitely scrollable nature of Web pages to produce a really cool infographic on the scales of orbital distances in the solar system.

So far, no moons found at Ceres or Vesta

Emily Lakdawalla • April 15, 2011

Since the Galileo mission discovered tiny Dactyl circling Ida in 1993, quite a lot of asteroid systems have been found to be binary; there are even a few triples. So it's quite reasonable to guess that two of the biggest asteroids, Ceres and Vesta, might also have satellites.

Saturn's storm: A quick turnaround from Hubble

Emily Lakdawalla • March 28, 2011

Saturn's raging northern storm has been watched since it began by amateur astronomers, and now Cassini is getting in to the act too. Presumably once astronomers realized the magnitude of what was going on, some of Earth's great observatories were also occasionally pointed at the ringed planet to watch the storm grow.
