LRO Reveals Lunar Pits Could Support Human Activity on the Lunar Surface

Lunar Pits Could Shelter Astronauts

New observations from NASA’s Lunar Reconnaissance Orbiter Spacecraft reveals that lunar pits on our moon could be used to shelter astronauts, supporting human activity on the lunar surface. This video shows images from NASA’s LRO spacecraft of various lunar pits. Image Credit: NASA’s Goddard Space Flight Center/D. Gallagher While the moon’s surface is battered by […]

Fermi Discovers a Pulsar That Switched from Radio Emissions to High-Energy Gamma Rays

Pulsar Switched from Radio Emissions to High Energy Gamma Rays

New measurements by NASA’s Fermi Gamma-ray Space Telescope reveal a binary star system whose pulsar switched from radio emissions to high-energy gamma rays. Zoom into an artist’s concept of AY Sextantis, a binary star system whose pulsar switched from radio emissions to high-energy gamma rays in 2013. This transition likely means the pulsar’s spin-up process […]

Dwarf Galaxy Movement Challenges to Our Understanding the Universe

New Study on Dwarf Galaxies May Force a Cosmic Rethink

A newly published study examines the movement of small galaxies throughout the universe, finding that they ‘dance’ in orderly disc-shaped orbits around larger galaxies. The discovery that many small galaxies throughout the universe do not ‘swarm’ around larger ones like bees do but ‘dance’ in orderly disc-shaped orbits is a challenge to our understanding of […]

Yale Researchers Discover New Cancer Cell Vulnerability

Researchers Discover New Cancer Cell Vulnerability

New research from Yale University found that simultaneous inhibition of both telomerase and p21 inhibited tumor growth in mice. Yale School of Medicine and Yale Cancer Center researchers have uncovered a genetic vulnerability of cancer cells that express telomerase — an enzyme that drives their unchecked growth — and showed that telomerase-expressing cells depend upon […]

Is the Universe a Bubble? – Physicists Work on the Multiverse Hypothesis

Perimeter Institute for Theoretical Physics Examines the Multiverse Hypothesis

In several new studies and a short video, researchers from the Perimeter Institute for Theoretical Physics detail their work on the multiverse hypothesis. Perimeter Associate Faculty member Matthew Johnson and his colleagues are working to bring the multiverse hypothesis, which to some sounds like a fanciful tale, firmly into the realm of testable science. Never […]

Hubble Views NGC 3501

Hubble Views Spiral Galaxy NGC 3501

This newly released Hubble image shows spiral galaxy NGC 3501. The thin, glowing streak slicing across this image cuts a lonely figure, with only a few foreground stars and galaxies in the distant background for company. However, this is all a case of perspective; lying out of frame is another nearby spiral. Together, these two […]

Scientists Experimentally Recreate Conditions That Exist Deep Inside Giant Planets

Scientists Experimentally Recreate Conditions That Exist Inside Giant Planets

Using the largest laser in the world, scientists were able to experimentally recreate the conditions that exist deep inside giant planets for the first time. Lawrence Livermore scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many of the planets recently discovered outside […]

“Nanocamera” Takes Pictures at Distances Smaller Than the Wavelength of Light

Nanocamera Takes Pictures at Distances Smaller Than the Wavelength of Light

A new study details how researchers used an array of novel gold, pillar-bowtie nanoantennas like traditional photographic film to record light for distances that are much smaller than the wavelength of light. Researchers at the University of Illinois at Urbana-Champaign have demonstrated that an array of novel gold, pillar-bowtie nanoantennas (pBNAs) can be used like […]

Astronomers Discover Evidence of How Giant Planets Form

Evidence of How Giant Planets Like Jupiter Form

Using Canada-France-Hawaii Telescope observations of 16 Cygni, astronomers discovered evidence of how giant planets like Jupiter form. One of the main models to form giant planets is called “core accretion”. In this scenario, a rocky core forms first by aggregation of solid particles until it reaches a few Earth masses when it becomes massive enough […]

First Detailed Analysis of Weak Lensing Dark Matter Peaks

The First Detailed Analysis of Weak Lensing Peaks

An international team of scientists present the first detailed analysis of the weak lensing peaks, finding that the abundance of peaks detected in CS82 is consistent with predictions from a Lambda cold dark matter cosmological model once noise effects are properly included. A number of studies have shown that Dark Matter is the principal mass […]

Hubble Image of the Day – “Mystic Mountain”

Hubble Image of the Day Mystic Mountain

First released in 2010, this Hubble image of the day shows “Mystic Mountain” within the Carina Nebula. This craggy fantasy mountaintop enshrouded by wispy clouds looks like a bizarre landscape from Tolkien’s The Lord of the Rings. The NASA/ESA Hubble Space Telescope image, which is even more dramatic than fiction, captures the chaotic activity atop […]

ATLAS Collaboration Detects Process Even Rarer Than Higgs Particle

ATLAS Collaboration Detects Process Even Rarer than the Higgs Particle

A new published study from the ATLAS Collaboration reports the first evidence of a process that can be used to test the mechanism by which the recently discovered Higgs particle imparts mass to other fundamental particles. Scientists running the ATLAS experiment at the Large Hadron Collider (LHC), the world’s largest and most powerful “atom smasher,” […]
