And what a difference from Saturn’s largest moon , Titan , whose atmosphere is not only thick , but packed with nitrogen and methane , with little trace of carbon dioxide or oxygen . Rhea’s tenuous exosphere , which includes carbon dioxide , is so thin that its density of oxygen is about five trillion times lower than that of Earth’s atmosphere . Even so , interesting things may happen on an icy surface in this . scenario

It was only a little over a year ago that the 400th extrasolar planet was confirmed, but time flies when you’re discovering exoplanets. The 19th of November 2010 marked the date that over 500 exoplanets had been confirmed on The Extrasolar Planets Encyclopedia. Though it’s an arbitrary number to celebrate, the fact that we’ve confirmed [...]

Russia is looking to build a $2 billion orbital “pod” that would sweep up satellite debris from space around the Earth. According to a post on the Russian Federal Space Agency, Roscosmos’ Facebook site, (which seems to confirm an earlier article by the Interfax news agency) the cleaning satellite would work on nuclear power and [...]
Last week we talked about Lyman Spitzer, and this week we’ll take a look at the orbiting observatory that bears his name: the Spitzer Space Telescope. Designed to see into the infrared spectrum, Spitzer has returned images of objects that were previously hidden to astronomers by thick shrouds of gas and dust. Click here to [...]
Is this galaxy exploding? Although that’s what it might look like, this is actually two gigantic galaxies crashing into each other. NGC 520 — also known as Arp 157 — is a mashup of two huge galaxies, now combining into one. We can’t really watch the process, as it happens extremely slowly — over millions [...]

Nuclear is the cheapest option at all carbon prices and the only one able to meet the stringent greenhouse gas emission targets envisaged for 2050. The three Australian authors wrote in a paper published this week in international peer-reviewed journal . Energy Cost , and the impact of carbon pricing on that cost , is analysed on the
In an earlier post, I wrote about ISEC awarding an Honorable Mention for the Artsutanov Prize.
Based on a re-review of all of the papers submitted for the competition, ISEC is very pleased to award a second Honorable Mention for the Artsutanov Prize, this to Karen Ghazaryan, S.A. Ambartsumian and M.V. Belubekyan for their paper “Optimal [...]
