Now a F*ckin' Space Science Thread

I hope Ms. Baker and her friend had to resign from Facebook because of this.

It is also approximately 7000 lightyears away and is speculated by scientists to have been destroyed thousands of years ago by a nearby supernova. Given the distance, it will take another 1000 years we will be able to see it's possible destruction.

Note to self: Local supernova 7K light years away will hit our vicinity in about one thousand years.

While is it not a "near-Earth supernova" I would reccomend not accepting offers of imortality in order to not have to worry about the impact to the planet in a thousand years, especially if we get caught in the path of the gamma ray burst.

This NASA/ESA Hubble Space Telescope image shows the center of globular cluster M 4. The power of Hubble has resolved the cluster into a multitude of glowing orbs, each a colossal nuclear furnace. M 4 is relatively close to us, lying 7200 light-years distant, making it a prime object for study. It contains several tens of thousands stars and is noteworthy in being home to many white dwarfs—the cores of ancient, dying stars whose outer layers have drifted away into space.

In July 2003, Hubble helped make the astounding discovery of a planet called PSR B1620-26 b, 2.5 times the mass of Jupiter, which is located in this cluster. Its age is estimated to be around 13 billion years—almost three times as old as the Solar System! It is also unusual in that it orbits a binary system of a white dwarf and a pulsar

Cool story, yo.

Any physicist in here?
I have a question.

Why can't I see stars in the "sky" in the video of Armstrong and Buzzdrin on the moon?

Makes sense for the same reason that dark spots on the sun aren't dark at all -- they're actually more than 100x brighter than a light bulb comparatively to the rest of the sun, but our eyes auto-adjust.

Oh, AoG, I bet you say that to all the guys.

On Sunday September 9, 2012 (still today for some of you), India’s Polar Satellite Launch Vehicle PSLVC-21 lifted off, carrying two satellites from a launch pad in Sriharikota, southern India. It was the 100th mission for the Indian Space Research Organisation (ISRO). The satellites consist of one French observation satellite and a Japanese microsatellite.

India’s space programme has been active since the 1960’s, launching satellites for India and other nations. The ISRO successfully sent a probe to the moon in 2008; it was the first time a probe had detected evidence of water on the lunar surface. There are plans to send a spacecraft to Mars next year.

Happy 100th to all you Indians who are too poor to have tvs or pcs.

M not a physicist but the reason in short is it takes time for a camera to adjust to the darkness. Of you took a photo of the sky all you'd see is black unles you held it at the sky for a certain period of time.

The Pencil Nebula is also known as NGC 2736 or Herschel's Ray, after the British astronomer who discovered it in 1835, John Herschel. It is a cloud of glowing gas that is part of a huge ring of wreckage left over after a supernova explosion that took place about 11 000 years ago. The nebula is found in the southern constellation of Vela (The Sails), is about 0.75 light years across and is about 800 light years from Earth. It moves through the interstellar medium around 650,000 kilometres per hour. The brightest part of the nebula resembles a pencil, hence its name; the entire structure in this image more resembles a witch’s broom.

The remnant from the Vela supernova is an expanding shell which originated from the supernova explosion. Initially the shock wave would have been moving at millions of kilometres per hour, but its expansion through space meant it ploughed through the gas between the stars, which slowed it down considerably. The Pencil Nebula is the brightest part of this shell. The luminous appearance of the nebula comes from dense gas regions struck by the supernova shock wave.

The different colours of the nebula allow astronomers to determine the temperature of the gas. Regions which glow blue are so hot that the emission is dominated by ionised oxygen atoms. Cooler regions glow red, due to hydrogen emission.

The image was produced by the Wide Field Imager on the MPG/ESO 2.2-metre telescope at ESO’s La Silla Observatory in Chile.
