Nasa's 'Halloween Nebula' Is Screaming For Your Soul, In Space

This picture was published by Nasa back in 2000, and shows the Perseus Cluster doing a fine impression of a flaming, screaming skull:

The image was taken by the Chandra Observatory using x-rays. It shows the Perseus cluster - one of the largest objects in the visible universe. Containing thousands of galaxies, the cluster is a cloud of very hot gas more than 50 million C in temperature, which is located a pleasantly-distant 320 million light years from Earth.

The bubbles that form the 'eyes' in the picture are areas clustered around a massive black hole in the centre, while the not is probably the 'shadow' of a galaxy in front of the cluster.

Wow beautiful images ravenslament, thanks for posting them

thanks joey , i like to share the beauty of the universe . to think all these pictures are of objects that are not of this planet , it makes me ponder that we are just a grain of sand on a beach in the vastness of space

I can't believe I've never looked at this thread before!!! The images really are stunning.....to be honest I only glanced at the title and stupidly thought it was astrology rather than astronomy!!! So I was very happy to see these pics and not Aries in Uranus

( I'm so stooopid sometimes

It amazes me that there are all these images to see and most people never ever get to see them,
there is so much out there and these images spark so many questions..........

Again thanks

excellent news

The BBC released the following statement earlier today:

"The BBC today announces that its longest running astronomy series, The Sky At Night, will continue next year. From February 2014, it will air in a new monthly half-hour slot on BBC Four, with repeats on BBC Two.

Kim Shillinglaw, Head of Commissioning for BBC Science and Natural History, says: “Sir Patrick Moore inspired generations of astronomers and I hope that alongside the BBC's other astronomy content, such as BBC Two’s Stargazing Live, The Sky at Night will enthuse further generations about the wonder of the night sky.”

Cassian Harrison, Editor for BBC Four, says: “I’m delighted that we are continuing with such a treasured BBC brand, and look forward to welcoming the programme to its new home on BBC Four, where it will join a rich mix of other science content.”

The Sky at Night was first broadcast on 24 April 1957 and continued to be presented by Sir Patrick Moore until his death in 2012, making it the longest-running programme with the same presenter in television history. Following Moore’s death, the series has been fronted by a team of guest presenters."

'Witch Head' Brews Baby Stars

A witch appears to be screaming out into space in this new image from NASA's Wide-Field Infrared Survey Explorer, or WISE. The infrared portrait shows the Witch Head nebula, named after its resemblance to the profile of a wicked witch. Astronomers say the billowy clouds of the nebula, where baby stars are brewing, are being lit up by massive stars. Dust in the cloud is being hit with starlight, causing it to glow with infrared light, which was picked up by WISE's detectors.

The Witch Head nebula is estimated to be hundreds of light-years away in the Orion constellation, just off the famous hunter's knee.

WISE was recently "awakened" to hunt for asteroids in a program called NEOWISE. The reactivation came after the spacecraft was put into hibernation in 2011, when it completed two full scans of the sky, as planned.

The six-member Expedition 37 crew is keeping busy with science experiments and maintenance while awaiting three new crew members, who launch aboard a Soyuz at 11:14 p.m. EST Wednesday and arrive at the space station Thursday. On Saturday, the Olympic torch -- delivered by Expedition 38 and returning home with Expedition 37 -- will be carried on a spacewalk. Flight Engineers Karen Nyberg and Luca Parmitano and Commander Fyodor Yurchikhin return to Earth on Sunday.

The sun emitted a significant solar flare, peaking at 5:12 p.m. EST on Nov. 5, 2013. Solar flares are powerful bursts of radiation. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however -- when intense enough -- they can disturb the atmosphere in the layer where GPS and communications signals travel.

Comet Ison Roars Through Leo

In the early morning of Oct. 25 (6:45 a.m. EDT), NASA's Marshall Space Flight Center in Huntsville, Ala., used a 14" telescope to capture this image of Comet C/2012 S1 (ISON), which is brightening as it approaches the sun. The comet shines with a faint green color just to the left of center. The diagonal streak right of center was caused by the Italian SkyMed-2 satellite passing though the field of view. At magnitude 8.5, the comet is still too faint for the unaided eye or small binoculars, but it's an easy target in a small telescope.

At this time of this image, ISON was located in the constellation of Leo the Lion, some 132 million miles from Earth and heading in toward the sun at 87,900 miles per hour.

Hubble's New Shot of Proxima Centauri, our Nearest Neighbor

Shining brightly in this Hubble image is our closest stellar neighbor: Proxima Centauri.

Proxima Centauri lies in the constellation of Centaurus (The Centaur), just over four light-years from Earth. Although it looks bright through the eye of Hubble, as you might expect from the nearest star to the Solar System, Proxima Centauri is not visible to the naked eye. Its average luminosity is very low, and it is quite small compared to other stars, at only about an eighth of the mass of the sun.

However, on occasion, its brightness increases. Proxima is what is known as a flare star," meaning that convection processes within the star’s body make it prone to random and dramatic changes in brightness. The convection processes not only trigger brilliant bursts of starlight but, combined with other factors, mean that Proxima Centauri is in for a very long life. Astronomers predict that this star will remain middle-aged — or a "main sequence" star in astronomical terms — for another four trillion years, some 300 times the age of the current Universe.

These observations were taken using Hubble’s Wide Field and Planetary Camera 2 (WFPC2). Proxima Centauri is actually part of a triple star system — its two companions, Alpha Centauri A and B, lie out of frame.

Although by cosmic standards it is a close neighbor, Proxima Centauri remains a point-like object even using Hubble’s eagle-eyed vision, hinting at the vast scale of the Universe around us.

3C353: Giant Plumes of Radiation

Jets generated by supermassive black holes at the centers of galaxies can transport huge amounts of energy across great distances. 3C353 is a wide, double-lobed source where the galaxy is the tiny point in the center and giant plumes of radiation can be seen in X-rays from Chandra (purple) and radio data from the Very Large Array (orange).
