A recently launched Earth-observing satellite is using the stars to practice its pointing, and caught a neat animation of Jupiter.
Scientists would like your help starting at high-resolution images of the Andromeda Galaxy captured by the Hubble Space Telescope.
The newly-released eXtreme Deep Field takes us even further back into the history of our universe than the Ultra Deep Field or UDF.
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.
There is an ever-expanding bubble announcing Humanity's presence to anyone listening in the Milky Way.
Cary and Michael Huang present a basic
The NuSTAR X-ray telescope will enable scientists to get a much-improved look at black holes and supernovae in both the Milky Way and other galaxies.
Last week, the team put all of the data from Deep Impact's deep-sky imaging session online, and challenged visitors to see what they could make from it. I made some photos of M51, but there were some challenges.
Citizen Science projects let volunteers easily contribute to active science programs. They're useful when there is so much data it overwhelms computing algorithms (if they exist) or the scientific research team attempting to process it.
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.
Space probes grant us perspective, the ability to see our place within the vastness of the solar system. But opportunities to see all of the solar system's planets in one observation are rare. In fact, there's only been one opportunity on one mission to see the whole solar system at once, until now.
Look at the center of this star-studded image and you'll find an emerald green dot.
Three years after New Horizons flew past Jupiter on its way to Pluto, the spacecraft has imaged the giant planet again.
What does a barred spiral galaxy look like? THIS is what a barred spiral galaxy looks like.
I'm pleased to point out that the Wide-field Infrared Survey Explorer mission (WISE) has started an
Congratulations are due to the Wide-field Infrared Survey Explorer (WISE) team on their lovely
On Monday, if all goes well, we will launch the Space Shuttle to rejuvenate one the greatest scientific missions launched on or off the Earth: the Hubble Space Telescope.
A very pretty picture of a moon among stars. Happy 2009, everyone!
I received the following question by email last week:
