Spitzer Reveals Possible “Rejuvenated” Planet

Evidence of a Rejuvenated Planet

NASA’s Spitzer Space Telescope has detected excess infrared light around white dwarf PG 0010+280. Scientists aren’t sure where the light is coming from, but one possibility is a rejuvenated planet. Future observations may help solve this mystery. For a planet, this would be like a day at the spa. After years of growing old, a […]

NASA Supercomputer Shows Exoplanet Making Waves in Nearby Debris Disk

NASA Supercomputer Shows Planet Making Waves

Astrophysicists have created a new supercomputer simulation of the planet and debris disk around the Beta Pictoris. The new supercomputer model reveals that the planet’s motion drives spiral waves throughout the disk, a phenomenon that causes collisions among the orbiting debris. Patterns in the collisions and the resulting dust appear to account for many observed […]

NASA Study Shows Beijing’s Physical Area Quadrupled between 2000 and 2009

Beijing Physical Area Quadrupled in Size in a Decade

Using data from NASA’s QuikScat satellite, a newly published study demonstrates how to quantify urban growth based on observed changes in physical infrastructure. Scientists used this new technique to study the rapid urban growth in Beijing, China, finding that its physical area quadrupled between 2000 and 2009. A team led by Mark Jacobson of Stanford […]

Hubble Telescope Views Nitrogen-Rich Planetary Nebula

Hubble Views Nitrogen-Rich Nebula

This newly released Hubble image shows planetary nebula NGC 6153, which is located about 4,000 light-years away in the southern constellation of Scorpius. The faint blue haze across the frame shows what remains of a star like the sun after it has depleted most of its fuel. When this happens, the outer layers of the […]

Floating Nuclear Power Plant that is Safer and Cheaper

The proposed Offshore Floating Nuclear Plant structure is about 45 meters in diameter, and the plant will generate 300 megawatts of electricity. An alternative design for a 1,100 MW plant calls for a structure about 75 meters in diameter. In both cases, the structures include living quarters and helipads for transporting personnel, similar to offshore oil drilling platforms.

Since nuclear power plants emit no carbon dioxide, they are considered an important component for a greener energy future. A new nuclear power plant promises to be safer, cheaper, and easier to deploy than current plants, but what makes it especially unique is that it will float eight or more miles out to sea. Many […]

Researchers Create Engineered Particles that Kill Harmful Bacteria

In this illustration, phagemid plasmids infect a targeted bacteria.

Deadly to targeted bacteria, engineered particles known as phagemids have been created to fight bacterial infections with great effectiveness while eliminating harmful side effects of more traditional treatments. The global rise in antibiotic resistance is a growing threat to public health, damaging our ability to fight deadly infections such as tuberculosis. What’s more, efforts to […]

Giant Galaxy Messier 87 is Still Growing

The huge halo around giant elliptical galaxy Messier 87 appears on this very deep image. An excess of light in the top-right part of this halo, and the motion of planetary nebulae in the galaxy, are the last remaining signs of a medium-sized galaxy that recently collided with Messier 87.

The image also reveals many other galaxies forming the Virgo Cluster, of which Messier 87 is the largest member. In particular, the two galaxies at the top right of the frame are nicknamed "the Eyes".

According to new observations with ESO’s Very Large Telescope, the giant elliptical galaxy Messier 87 has swallowed an entire medium-sized galaxy over the last billion years. This is the first time a team of astronomers has been able to track the motions of 300 glowing planetary nebulae to find clear evidence of this event. They […]

“Behemoth” Bleeding Atmosphere Around a Warm Exoplanet Discovered by Hubble

This artist's concept shows "The Behemoth," an enormous comet-like cloud of hydrogen bleeding off of a warm, Neptune-sized planet just 30 light-years from Earth. Also depicted is the parent star, which is a faint red dwarf named GJ 436. The hydrogen is evaporating from the planet due to extreme radiation from the star. A phenomenon this large has never before been seen around any exoplanet.

An enormous cloud of hydrogen is bleeding off the warm exoplanet GJ 436b due to exreme radiation from it’s star. The huge cloud is about 50 times the size of the star, and has been dubbed “The Behemoth” by astronomers. Astronomers using NASA’s Hubble Space Telescope have discovered an immense cloud of hydrogen dubbed “The […]

Discovery May Lead to New Crack-resistant Metal Alloys

The image shows corrosion of a silver-gold alloy spontaneously resulting in the formation of nanoscale porous structures that undergo high-speed cracking under the action of a tensile stress. It helps demonstrate a discovery by an Arizona State University research team about the stress-corrosion behavior of metals that threatens the mechanical integrity of engineered components and structures.

A new discovery by researchers at Arizona State Univeristy points the way to designing crack-resistant metal alloys with different microstructures. Sometimes looking at something at the smallest scale can lead to solutions to big problems. A recent study into the interactions of metal alloys at the nanometer and atomic scales is likely to aid advances […]

Study Shows Medical Marijuana ‘Edibles’ Mostly Mislabeled

Study Shows Medical Marijuana Edibles Mostly Mislabeled

In a study led by Johns Hopkins, researchers reviewed the THC content of a small sample of dispensary products. They found the vast majority of them either understated or overstated the cannabinoid content on the label, suggesting buyers are at risk of overdosing or being cheated. Fast Facts: Although laws in some states now permit […]

How Laser Frequency Combs Transformed Basic Scientific Research

Precision rulers of light (laser frequency combs) span millions of frequencies of light, and can operate from the mid-infrared through the visible to the extreme ultraviolet. They are at the heart of new technologies such as optical atomic clocks, molecular fingerprinting and a noninvasive breath analyzer.

Although most people have never heard of laser frequency combs, they have become essential to advancing important light-based research and have been instrumental to the development of new technologies over a wide range of applications. It almost sounds like a riddle: What tool has transformed basic scientific research and led to new technologies in so […]
