Hubble’s view of an ancient raging storm on Jupiter
This mosaic presents a series of pictures of the Red Spot obtained by Hubble between 1992 and 1999. This Great Red Spot is present in Jupiter’s atmosphere for more than 300 years. It is now known that it is a vast storm, spinning like a cyclone. The Red Spot rotates in a counterclockwise direction in the southern hemisphere, showing that it is a high-pressure system. Winds inside this Jovian storm reach speeds of about 270 mph.
The Red Spot is the largest known storm in the Solar System. With a diameter of 15,400 miles, it is almost twice the size of the entire Earth and one-sixth the diameter of Jupiter itself.
The long lifetime of the Red Spot may be due to the fact that Jupiter is mainly a gaseous planet. It possibly has liquid layers but lacks a solid surface, which would dissipate the storm’s energy, much as happens when a hurricane makes landfall on the Earth. However, the Red Spot does change its shape, size, and color, sometimes dramatically.

Less Than a Week Remains Before NASA’s Biggest Rover Yet Lands on Mars
NASA’s newest Mars rover is less than a week away from its high-stakes landing on the surface of the Red Planet.
The Mars Science Laboratory (MSL) Curiosity rover is scheduled to touch down on Mars at 10:30 p.m. PDT on Aug. 5 (1:30 a.m. Aug. 6 EDT, 0530 GMT). The car-size robotic explorer is designed to investigate whether Mars is, or ever was, capable of hosting microbial life.
With six days to go until Curiosity arrives at the Red Planet, project managers are bracing themselves for what NASA calls the riskiest part of the mission: the rover’s harrowing descent through the Martian atmosphere to the ground.
Oh Neil, once again you blow my mind with your sense-talking.
A must watch for everyone. The latter half provides a wonderful point of view.
Thank you for making the numbers in your song accurate, Monty Python.
“Earth revolves at 900 miles an hour”
“Earth orbits around the sun at 19 miles a second”
“Nearby solar systems plus ours moves around the center of the Milky Way at 1,000,000 miles a day via 40,000 miles an hour”
“The Milky Way contains 100,000,000,000 stars”
“The Milky Way is 100,000 lightyears long”
“The centre of the Milky Way is 60,000 lightyears wide, but the spiral arm in which Sol is located is only 3,000 lightyears wide”
“We’re 30,000 lightyears from galactical central point”
“We orbit around said galactic central point every 200,000,000 years”
Almost all of these were legitimate answers to questions on my Astronomy final last semester, and thanks to Monty Python, I did well.
Must have been strange muttering and humming that song to myself while taking the exam, tho.
The Philosopher’s Song, on the other hand, was less useful to me in my philosophy exams…
Into the Sword of Orion
Distance: 1500 Light Years

The region of Orion and Monoceros has unique importance as one of the great regions of active star formation in our galaxy.
Its proximity and favorable position in the sky have made this one of the most extensively studied regions in the Milky Way.

One thing I’m kinda’ fed up with reading on here are all the posts complaining about Pluto not being a planet any more. Educate yourselves, people, if you feel THAT passionately about it…educate yourselves! Pluto IS a planet, it’s merely been reclassified as a dwarf planet, of which there are at least five in our solar system, but possibly as many as nine. At least one of them, Eris, is actually bigger than Pluto. So if you’re going to argue that Pluto should be classified as a planet, then Eris should be too.
Rather than complaining that there are now only eight planets instead of nine, how about you get excited about the fact that, if you include all of the dwarf planets, there are seventeen planets in our solar system! How cool is that?
So stop grumbling about Pluto’s reclassification and, instead, give some love to Ceres, Haumea, Makemake, Eris, Orcus, Quaoar, 2007OR10 and Sedna instead!
Indeed…wouldn’t your energies be better expended on lamenting the lack of a proper name for poor old 2007OR10?
Just look at it…

…doesn’t it deserve a better name?
