The Search for Variable Stars in Globular Cluster M4

In a newly published study, astronomers detail the results of a photometric search for variable stars in the core of the globular cluster M4. A globular cluster is a roughly spherical ensemble of stars, as many as several million of them, gravitationally bound together in groups whose diameters can be as small as only tens […]

Supercomputer Simulations Open the Door for Numerical Modeling of Nuclear Interactions

Researchers from RIKEN detail the first supercomputer simulations of ‘spin–orbit’ forces between neutrons and protons in an atomic nucleus, opening the door for numerical modeling of nuclear interactions. Protons and neutrons are held together at the center of an atom by powerful nuclear forces. A theory that can describe the interaction between just two of […]

Astronomers Map Galaxy Cluster More Precisely Than Ever Before

Astronomers used almost 200 images of distant galaxies combined with Hubble data to measure the total mass of galaxy cluster MCS J0416.1–2403 more precisely than ever before. Astronomers using the NASA/ESA Hubble Space Telescope have mapped the mass within a galaxy cluster more precisely than ever before. Created using observations from Hubble’s Frontier Fields observing […]

New Images and 3D Model of Comet 67P

New images from ESA’s Rosetta spacecraft reveal surface structures of comet 67P/Churyumov-Gerasimenko, allowing scientists to create a 3D shape model of the nucleus. As the European Space Agency’s Rosetta probe approaches Comet 67P/Churyumov-Gerasimenko (67P) for an August rendezvous, the comet’s core is coming into sharper focus. Today, ESA released a new set of images and […]

New ESO Image of Star Cluster NGC 3293

This newly released image from ESO’s La Silla Observatory in Chile shows star cluster NGC 3293, which is located 8,000 light-years from Earth in the constellation of Carina. In this striking new image from ESO’s La Silla Observatory in Chile young stars huddle together against a backdrop of clouds of glowing gas and lanes of […]

New Terahertz Modulator Could Lead to More Advanced Medical and Security Imaging

Researchers from UCLA have developed a terahertz modulator that performs across a wide range of the terahertz band with very high efficiency and signal clarity, which could eventually lead to more advanced medical and security imaging systems. A UCLA Henry Samueli School of Engineering and Applied Science research team has developed a breakthrough broadband modulator […]

Most Precise Measurement Ever of the Radius of a Planet Outside Our Solar System

Scientists have made most precise measurement ever of the radius of a planet outside our solar system, confirming Kepler-93b as a “super-Earth” that is about one-and-a-half times the size of our planet. Thanks to NASA’s Kepler and Spitzer Space Telescopes, scientists have made the most precise measurement ever of the radius of a planet outside […]

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 […]
