Planetary nebulae represent a final brief stage in the life of a star like the Sun. While consuming the last of the fuel in its core, the star expels a large portion of its outer regions, which then heats up and glows brightly, showing intricate structures that scientists are still trying to fully understand.
Astronomers using the Hubble Space Telescope have found seven galaxies that formed relatively shortly after the universe's birth some 13.7 billion years ago, scientists said on Wednesday, describing them "as baby pictures of the universe."
A pair of NASA moon-mapping probes smashed themselves into a lunar mountain on Monday, ending a year-long mission that is shedding light on how the solar system formed. The Gravity Recovery and Interior Laboratory, or GRAIL, spacecraft had been flying around the moon, enabling scientists to make detailed gravity maps.

The deal was sold to New Mexicans in classic Richard Branson fashion. If taxpayers would build the colorful British businessman a $209 million futuristic spaceport, he would make New Mexico the launching point for a space tourism business catering to the rich and famous.
OSI Laser Diode, Inc. (LDI) introduces a product family of high power monolithic stack pulsed laser diodes for a wide variety of military/defense, industrial, automotive, and machine vision applications. Single and stacked pulsed laser diodes are available up to 375W and fiber-coupled devices are available up to 188W. Custom packaging is also available, upon customer request.
The military's small, top-secret version of the space shuttle rocketed into orbit Tuesday for a repeat mystery mission, two years after making the first flight of its kind. The Air Force launched the unmanned spacecraft Tuesday hidden on top of an Atlas V rocket. As if on cue, clouds quickly swallowed up the rocket as it disappeared out over the ocean.
Schaefer announces new 19” rack mount configurations for their Raptor Series of military power supplies. The Raptor’s robust construction and high reliability make it an ideal choice for harsh military applications such as shelters, armored vehicles, avionics, naval and open air applications.
A secret agent is racing against time. He knows a bomb is nearby. He rounds a corner, spots a pile of suspicious boxes in the alleyway, and pulls out his cell phone. As he scans it over the packages, their contents appear onscreen. In the nick of time, his handy smartphone application reveals an explosive device, and the agent saves the day
Professor Alan Alda has a homework assignment for scientists. Yes, that Alan Alda. The actor known for portraying Capt. Benjamin Franklin "Hawkeye" Pierce on the TV show "MASH" and more recent guest shots on NBC's "30 Rock" is also a visiting professor at New York's Stony Brook University school of journalism
A Russian billionaire's foundation is awarding two special prizes of $3 million each to British cosmologist Stephen Hawking for his work on black holes and to seven scientists at the world's biggest atom-smasher for their roles in the discovery of a new subatomic particle believed to be the long-sought Higgs boson.
Unmanned underwater vehicles (UUV) and sonobuoys continue to occupy a critical role in undersea warfare, and the design of such technologies – especially with regard to their power systems – is acutely important due to their growing indispensability to a variety of tactical defense operations.
British astronomer and broadcaster Patrick Moore died Sunday, according to friends and colleagues. He was 89. He died at his home in the coastal town of Selsey in southern England, according to a statement released Sunday. No specific cause of death was given,
Behlman Electronics solved a vexing 1500 VA power supply problem sometimes experienced by US Air Force personnel when they must reprogram munitions in the field, and it grew into a 5000 VA solution for this and other applications, as well.
International Rectifier introduced a series of high current, ultra-low dropout (ULDO) RAD-Hard hybrid linear voltage regulators available in Standard Microcircuit Drawings (SMD) for space applications including satellites and launch vehicles.
Asteroids and comets colliding with the moon not only pitted its surface but also severely fractured its crust, researchers with NASA said on Wednesday, in a finding that could help crack a Martian puzzle. On Mars, similar fracturing would have given water on the surface
A team of former NASA executives is launching a private venture to send people to the moon for a price that is definitely out of this world. For $1.5 billion, the newly formed business is offering countries a two-person trip to the moon, either for research or national prestige. The venture was announced Wednesday.
Twin spacecraft have captured the clearest sounds yet from Earth's radiation belts - and they mimic the chirping of birds.NASA's Van Allen Probes have been exploring the hostile radiation belts surrounding Earth for just three months. But already, they've collected measurements of high-energy
If you thought NASA's latest Mars landing was a nail-biter, get ready for a sequel.The space agency on Tuesday announced plans to launch another mega-rover to the red planet in 2020 that will be modeled after the wildly popular Curiosity.To keep costs down, engineers will borrow Curiosity's
NASA's Mars rover Curiosity, dispatched to look for the chemical ingredients and environments for microbial life, has found hints of carbon, though whether this building block for life on Earth has played a similar role on Mars is unknown, scientists said on Monday.
The unstoppable Voyager 1 spacecraft has sailed into a new realm of the solar system that scientists did not know existed. Voyager 1 and its twin, Voyager 2, have been speeding away from the sun toward interstellar space, or the space between stars. Over the summer, Voyager 1, which is farther along in its journey,
TWIE 125: Non-Lethal Missile Knocks Out Electronics: This Week in Engineering - Seismologists convicted of manslaughter; finding damaged nuclear cores; power outage missile; robot tightrope-walker; testing bridges with rain; and bricks from cow blood.
The United Kingdom’s Defence Infrastructure Organisation (DIO) has awarded IBM with a contract that will help it gain greater insight and intelligence in relation to its entire property portfolio. DIO, an operational arm of the Ministry of Defence (MoD), is responsible for the management of some 4,000 separate sites....
NASA is looking for new ideas on what to do with two space telescopes left over from a once-secret U.S. spy satellite program.The U.S. space agency asked the scientific community on Tuesday for its input into possible missions for a pair of space telescopes donated last year to NASA by the National Reconnaissance Office
