A supernova that signals the death of a massive star sends titanic shock waves rumbling through interstellar space. An ultra-dense neutron star is usually left behind, which is far from dead, as it spews out a blizzard of high-energy particles. Two new images from NASAs Chandra X-ray Observatory provide fascinating views including an enigmatic lobster-like feature of the complex aftermath of a supernova.

When a massive star runs out of fuel, the central regions usually collapse to form a neutron star. The energy generated by the formation of the neutron star triggers a supernova. As the outward-moving shock wave sweeps up interstellar gas, a reverse shock wave is driven inward, heating the material ejected by the star.

Meanwhile, the rapid rotation and intense magnetic field of the neutron star, a.k.a. a pulsar, combine to generate a powerful wind of high-energy particles. This so-called pulsar wind nebula can glow brightly in X-rays and radio waves.

A long observation with Chandra of the supernova remnant MSH 11-62 (above) reveals an irregular shell of hot gas, shown in red, surrounding an extended nebula of high energy X-rays, shown in blue. Even though scientists have yet to detect any pulsations from the central object within MSH 11-62, the structure around it has many of the same characteristics as other pulsar wind nebulas. The reverse shock and other, secondary shocks within MSH 11-62 appear to have begun to crush the pulsar wind nebula, possibly contributing to its elongated shape. (Note: the orientation of this image has been rotated by 24 degrees so that north is pointed to the upper left.)

MSH 11-62 is located about 16,000 light years from Earth. The foreground of MSH 11-62 is speckled with hundreds of sources associated with the open stellar cluster Trumpler 18, located at a distance of about 5,000 light years, revealing a vast collection of stars.

The supernova remnant G327.1-1.1, located about 29,000 light years from Earth, is another spectacular debris field left behind when a massive star exploded. The Chandra image of G327.1-1.1 (below) shows the outward-moving, or forward, shock wave (seen as the faint red color), and a bright pulsar wind nebula (blue). The pulsar wind nebula appears to have been distorted by the combined action of the reverse shock wave, which may have flattened it, and by the motion of the pulsar, which created a comet, or lobster-like tail. An asymmetric supernova explosion may have given a recoil kick to the pulsar, causing it to move rapidly and drag the pulsar wind nebula along with it.

M. BASKETBALL | Red Heads to Charleston After First Home Victory

Posted on by

By AMIR PATEL

Just three games into the season and the Cornell mens basketball team has already made it clear that last years woes are a distant memory. The Red equaled its 2013-14 win total in just the first home game of the season, as it knocked off regional rival Colgate, 58-52 on Tuesday night.

The win highlighted the squads offensive depth, defensive tenacity and willingness to run the floor, all of which will be tested against top competition at the Charleston Classic.

Our guys have been executing the game plan well so far. We have stressed rebounding as a key to our success and our guys have done well at it, said head coach Bill Courtney.

The return of All-Ivy First Teamer Shonn Miller, along with senior guard Galal Cancer, has proven to be a difference maker for the Red early in the season. After scoring 21 and 20 points in the first two games, Miller was held to six against Colgate, but his impact was felt throughout the game nevertheless. As a forward with the ability to stretch the floor and hit outside shots, the respect that defenses are forced to give him allowed openings for guards like Cancer and senior Devin Cherry to attack the rim. Against Colgate, Cherry stepped up with 21 points and five assists to lead the offense.

The game was fast-paced and physically intensive, forcing the Red to use a balanced bench attack to help it come back from a 17-point deficit. After scoring a combined total of nine points in its first two games, the Cornell bench doubled that amount against Colgate. Sophomore guard JoJo Fallas scored eight points and freshman forward Wil Bathurst chipped in four points and four boards in 18 minutes of work.

We fought hard throughout the game. Having been down on the road against Loyola, we knew what was necessary and stepped up. Our guys stepped up the intensity in the second half to get us back in it, Courtney said.

The Charleston Classic will be a significant early season test for the Red, with four big-name conference teams in the field USC, Miami (FL), Penn State and South Carolina. The Red is in the bottom half of the bracket and is 13-point underdogs for the first game against South Carolina, which returns 11 players from last years team that finished second to last in the SEC for the second year in a row. The Gamecocks do return highly-touted shooting guard Sindarius Thornwell, who finished second on the team in scoring last season.

We are looking forward to challenging games in the tournament. There are several top teams at the event and I am looking forward to great competition. Our play is improved so far, and we want to keep that going in Charleston, Courtney said.

The top half of the Charleston Classic bracket features USC, a team that is coming off a season in which it finished last in the PAC 12. The Trojans bring in top freshman point guard Jordan McLaughlin, who was the No. 41 ranked recruit out of high school according to ESPN. Miami, a team that had a down season last year after losing 2013 ACC Player of the Year Shane Larkin to the NBA, is also in the top half of the bracket. The Canes also welcome a top point guard in JaQuan Newton, the No. 58 overall recruit according to ESPN.

The Red Dwarf star Craig Charles has left Im a Celebrity Get Me Out Of Here! following the sudden death of his brother.

The Coronation Street actor was missing from the live section of Wednesdays show after he was told about the death of his older brother Dean, who reportedly died after having a heart attack at his home in Spain.

Charles, 50, was not seen with his fellow contestants when presenters Ant and Dec entered the campsite. Earlier, the duo told viewers they could not vote for Charles when deciding which celebrity should take part in the next bushtucker trial.

An ITV spokesman said: Craig decided to leave the camp earlier today and will be heading back to his family in the UK. We send our sincere condolences to Craig and his family.

Meanwhile, The Only Way Is Essex star Gemma Collins told fellow campers the show had put her off TV for life after she quit the jungle. She left after managing just three days while grumbling about hunger and complaining that she thought she might have malaria.

Collins will be replaced in the jungle by former Conservative MP Edwina Currie and X Factor reject Jake Quickenden, who arrive on screens on Thursday night.

She said she had no regrets about taking part and suggested she would refocus her life as she declared: I believe that this is the start of me now, and nothing is going to change it.

Collins follows past contestants Brian Conley, Nigel Havers and Katie Price in leaving the show early.

Explaining her decision to go, she said: I have to start living my life the way I want to live it and this isnt it. Do you know what, I dont want any of this, I just dont want to have to put myself through such extreme measures all the time. I just want to be normal.

Ohio Senate Passes Red Light Camera Restrictions

Posted on by

COLUMBUS, Ohio - A bill that could mean the end of red light cameras in Columbus is one step closer to becoming law.

Wednesday the Ohio Senate passed new legislation on red light cameras that would require a police officer to be present for tickets to be issued from red light cameras.

"The cameras are on 24/7 365 without taking a day off," City of Columbus Public Safety Deputy DirectorGeorge Speaks. Cameras that capture images of hundreds of drivers plowing through red lights.

"Someone ran a red light. Receives a ticket and in Columbus you pay $95. That person then has 95 reasons not to run that red light again," Speakssaid.

But now Speaks believes the red light photo program he helped launch nearly 10 years ago could soon go away because of senate bill 342 and the statewide lawsuit that says the cameras are unconstitutional.

That lawsuit is now being reviewed by the Ohio SupremeCourt.

Speaksbelieves the solution to the photo red light issues would be for other counties to model the practices laid out here in Columbus,"Those practices would eliminate some of the allegations that have occurred in some if the smaller districts that are utilizing this technology for speed enforcement."

Lawmakers say the bill addresses the legal issues that came to light once red light cameras popped up in Ohio. State Senator Bill Seitz is sponsoring the bill.

NBC 4 reached out for comment Thursday but did not get a response.

Speaks says if the bill becomes law it will effectively end the red light camera program in Ohio.

Marshall Space Flight Center: A tour through NASA's hidden gem

Posted on by

One of NASAs more off-the-radar facilities is responsible for some of the organizations most important research. Kennedy Space Center and the Jet Propulsion Laboratory may get the lion's share of attention, but Marshall Space Flight Center, in Huntsville, Alabama, is responsible for developing much of the complex inner-workings of rockets, satellites, and future technologies.

The George C. Marshall Space Flight Center, to give it its full title, is actually the largest of NASA's various centers. Ever since it officially opened on July 1, 1960, after President Eisenhower approved the transfer of all Army space-related activities to NASA, it has been the space agency's lead center for the development of rocket propulsion systems and technologies, including the Saturn family of launch vehicles. Today, the center is engaged in propulsion and space transportation, engineering, science, space systems and space operations, and project and program management.

This includes NASAs 3D printing technology and research. Parts of the development for the recently launched 3D printer in space from Made In Space, occurred in Huntsville.

Also, the development of many designed-for-3D components, like engine elements, attachment mechanisms, and fueling systems, are being designed and printed on-site. These components are not only advancing these technologies, but they are also helping NASA lessen the weight of the components and reduce the cost of prototyping and manufacturing.

Reducing weight, and therefore cost, is a major focus for space research, and 3D printing promises to enable big savings in this are, making additive manufacturing, arguably, the most important technology being explored at NASA.

NASAs Space Launch System (SLS) is the next step in getting astronauts into deep space, with the organization setting its sights on Mars. The Orion spacecraft, which is expected to launch in December on a Delta IV launch vehicle, is planned to eventually launch on the SLS.

According to Marshall Space Flight Center, "SLS is the first rocket and launch system in history capable of powering humans, habitats, and space systems beyond our moon and into deep space.

The SLS components are constructed and tested at Marshall Space Flight center, and standing inside the hollow innards of a ring of the SLS is an intimidating and overwhelming experience. Within the testing room, adjacent to the massive ring of computer racks and components, the facility engineers run launch simulations and throw everything they have at the systems that will be part of the rocket. Everything from weather and wind changes to failing engines and misfires are simulated in both algorithms and 3D visualizations.

Perhaps the most interesting, yet little known, part of NASAs Marshall Space Flight Center is the fact that the facility houses the International Space Station (ISS) Payload Operations Integration Center & Laboratory Training Complex. Like a modernized scene out of Apollo 13, the control room houses an array of specialists working on everything from communications to systems analysis to experiment monitoring.

A wall of monitors presents various high-definition views from the numerous cameras onboard the ISS, while others provide a visualization of the several experiments happening live many of which are only operated from the ground, not by astronauts aboard the ISS.
