The planet is about twice the diameter of our own Earth with a mass about 5 times that of Earth. We would probably feel rather heavy on that one.

When will we see the next one ? I am sure there are others within our range.

The two planets, one estimated to be in the order of Earth sized, the other Moon sized , appear to have collided probably a few thousand years ago, very recent in astronomical terms.

More detail can be found at Bad Astronomer Blog

This is, as far as I know, the first, however indirect, evidence of Earth/Moon sized planets.

That is not all : A few days ago it was reported that the Kepler Space Telescope, launched this year, had detected the atmosphere of a planet orbiting another star

Exciting times indeed.

With that type of bursts we look back in time, this time more than 13000 million years, this belongs to the earliest generations of stars in the known Universe. Impressive.

I particularly like the “boiled down” version of the reply :

“Without imagination, science is a dictionary”

since without imagination science (and technology would never have brought us anywhere, certainly we would not be discussing the topic on the Internet.

For me Star Trek was a breakthrough in Science Fiction on TV and gave rise to a new trend – stating social issues in SF on TV. Actually, it was, at the time, the only way of tackling issues as racism, discrimination etc in TV series, by disguising it as “alien versus human” encounters. Majel is best known by SF fans from a multitude of roles in the Star Trek universe, and a single beautiful role in Babylon 5.

While it is sad to see someone pass beyond the Rim we should also remember the things she gave to us , in Star Trek : “Number One” from the original pilot, Nurse Chapel from the original series, Lwaxana Troi in The Next Generation, and the computer voice in all the “new” series, and from Babylon 5 the Lady Morella, seer and a wife of the deceased Emperor of the Centauri Republic.

With Starstuff I will quote the wonderful line she was given by Babylon 5 creator J. Michael Straczynski : “There is always choice. We say there is no choice only to comfort ourselves with the decision we have already made. If you understand that, there’s hope. If not ..” – Lady Morella, Babylon 5, »Point of no return«

Rest in peace Majel Barrett, and may you meet your Gene in a place where no shadows fall.

It comes due to the Martian Winter fast approaching, the solar panels are unable to keep the batteries charge…. and it is a little tricky to send someone to run a generator or change the batteries.

In a sense it is sad to lose a spacecraft, but Phoenix had done what it was supposed to do, and was operational for 2 months longer than its original 3 months mission. Not bad at all. The Odyssey orbiter appears to continue functioning, so not all is over yet, even if we are unlikely to hear it for some time while Mars passes behind the Sun (from our perspective).

This can be very interesting as water supply when (yes, I am optimistic) we send people to Mars – they do not have to bring large supplies of water. Could it be that – with care – the people going there can be self supporting with water supply ? Quite possible.

This is also a sign that Mars has had much more water than it has today. Maybe it even had an atmosphere dense enough to support life, more or less as we know it.

Full story.

Around the star Formalhaut Hubble found a ring of dust, corresponding to the Kuiper Belt in our own solar system. an Anomaly in the shape of the ring indicated that the gravitational pull of a planet influenced the ring. The hunt was on.

Two images taken 21 months apart show an object following the star and apparently orbiting Formalhaut in about 870 years.

Before we get too excited, there is no real chance of finding any ET’s in the Formalhaut system. The star is only 200 million years old and burning fast – the life expectancy is only 1000 million years, not enough for life as we know it to develop.

There are indications of further planets around Formalhaut, this time inside the dust ring, but none are observed yet.

More details from ESA’s website

On Friday the Moon Impact Probe was released for a crash landing near the Moon’s South Pole. While diving the impactor sent images and telemetry back to the orbiter, those will be relayed back to Earth at a slower pace. The descent took about 25 minutes and the data will be relayed in the next few days.

Instruments are beginning to be activated, and a new chapter in the lunar exploration is beginning.

The probe has already sent some very good images back, see link below.

Lunar images from Chandrayaan

The space craft is “Chandrayaan 1″. The name means “Moon Craft” in the ancient Sanskrit” language of India.

What I like is that the Indians, unlike the Chinese and Japanese, have invited other countries to contribute instruments to the probe. More than half of them are Indian, but NASA has two sensors, ESA has three sensors and Bulgaria has contributed a radiation sensor.

Chandrayaan 1 will help create a map of mineral concentrations all over the Moon, paving the way for the decisions on where to send (manned) expeditions to the Moon.

This and other collaborations is what I think has to be done. Space exploration is expensive, and a single country, however rich, cannot afford to go it alone.
