Hubble Reveals That Three Hot Jupiters Are Surprisingly Dry

Using the Hubble Space Telescope, astronomers reveal that three exoplanets that were thought to be ideal candidates for detecting water vapor in their atmospheres contain far less water than predicted by standard planet-formation theories. Astronomers using NASA’s Hubble Space Telescope have gone looking for water vapor in the atmospheres of three planets orbiting stars similar […]

A New Approach in the Search for Extraterrestrial Intelligence

Scientists are taking a new approach in the search for extraterrestrial intelligence, studying exoplanet atmospheres for signs of pollution. Cambridge, Massachusetts – Humanity is on the threshold of being able to detect signs of alien life on other worlds. By studying exoplanet atmospheres, we can look for gases like oxygen and methane that only coexist […]

Scientists Develop Membrane that Responds to Solvent Vapor

Material scientists have produced a membrane that curls very quickly when it comes into contact with the vapor from organic solvents, imitating biological structures which respond to an external stimulus like the Venus flytrap. An artificial skin now presented by a team working with scientists from the Max Planck Institute of Colloids and Interfaces in […]

No New Cosmological Concordance with Massive Sterile Neutrinos

A newly published study shows that modifying the standard cosmological model in order to include fairly massive neutrinos does not explain all the physical observations simultaneously. Neutrinos, also known as ‘ghost particles’ because they barely interact with other particles or their surroundings, are massless particles according to the standard model of particle physics. However, there […]

NASA Releases Four New Images to Celebrate Chandra’s 15th Anniversary

To celebrate Chandra’s 15th anniversary, NASA has released four new images of supernova remnants – the Crab Nebula, Tycho, G292.0+1.8, and 3C58. Fifteen years ago, NASA’s Chandra X-ray Observatory was launched into space aboard the Space Shuttle Columbia. Since its deployment on July 23, 1999, Chandra has helped revolutionize our understanding of the universe through […]

Hubble Probes the Extreme Outskirts of Elliptical Galaxy Centaurus A

A team of scientists used the Hubble Space Telescope to probe the outskirts of elliptical galaxy Centaurus A, revealing that the galaxy’s halo spreads far further into space than expected. Astronomers using the NASA/ESA Hubble Space Telescope have probed the extreme outskirts of the stunning elliptical galaxy Centaurus A. The galaxy’s halo of stars has […]

Astronomers Discover Transiting Exoplanet with Longest Known Year, Kepler-421b

Astronomers from the Harvard-Smithsonian Center for Astrophysics have discovered a transiting exoplanet with the longest known year, circling its star once every 704 days. Cambridge, Massachusetts – Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 […]

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

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

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

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

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

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 […]
