Mars Express Image of the Rim of the Schiaparelli Crater

New Image of Schiaparelli Basin from Mars Express

This image from ESA’s Mars Express features the small crater embedded in the northwestern rim of the Schiaparelli impact basin. All around is evidence for past water and the great martian winds that periodically blow. A 42 km-wide impact crater and numerous smaller craters straddle the northwestern rim of the 460 km-diameter Schiaparelli basin in […]

Chandra Views the “Cheshire Cat” Group of Galaxies

Chandra Views the Cheshire Cat Galaxies

This new image from NASA’s Chandra X-ray Observatory shows the group of galaxies nicknamed the “Cheshire Cat.” X-rays from Chandra show that the two “eye” galaxies and the smaller galaxies associated with them are slamming into one another in a giant galactic collision. One hundred years ago this month, Albert Einstein published his theory of […]

Hubble Image of the Week: Galaxy 2MASX J16270254+4328340

Hubble Views Galaxy 2MASX J16270254+4328340

This newly released Hubble image shows galaxy 2MASX J16270254+4328340, which is located in the Hercules constellation. This curious galaxy — only known by the seemingly random jumble of letters and numbers 2MASX J16270254+4328340 — has been captured by the NASA/ESA Hubble Space Telescope dancing the crazed dance of a galactic merger. The galaxy has merged […]

Physicists Achieve Quantum Entanglement at Room Temperature

Quantum Entanglement Achieved at Room Temperature

A newly published study from the University of Chicago and Argonne National Laboratory demonstrates how macroscopic entanglement can be generated at room temperature and in a small magnetic field. Entanglement is one of the strangest phenomena predicted by quantum mechanics, the theory that underlies most of modern physics: It says that two particles can be […]

New Horizons Views Pluto and Charon’s Daily Rotation

New Horizons Views Pluto Rotating Over the Course of a Full Pluto Day

NASA’s New Horizons Spacecraft has captured images of Pluto and Charon completing the rotation of a full day. Pluto’s day is 6.4 Earth days long. The images were taken by the Long Range Reconnaissance Imager (LORRI) and the Ralph/Multispectral Visible Imaging Camera as the distance between New Horizons and Pluto decreased from 5 million miles […]

Astronomers Study the Star Formation Rates of Galaxies

The Schmidt Law in Six Galactic Massive Star-forming Regions

In a newly published study, astronomers from the Harvard-Smithsonian Center for Astrophysics counted up the new stars in RCW106 and five other local regions of active star formation to check the reliability of estimating star formation rates in other galaxies by measuring their gas content and infrared emission. Our Milky Way galaxy produces on average […]

Tiny Red Dwarf Star Has a Magnetic Field Several Hundred Times Stronger Than Our Sun

ALMA Reveals Ultracool Star That is Super Stormy

Using the Atacama Large Millimeter/submillimeter Array, astronomers reveal that red dwarf star TVLM 513-46546 has an amazingly powerful magnetic field. Our Sun is a relatively quiet star that only occasionally releases solar flares or blasts of energetic particles that threaten satellites and power grids. You might think that smaller, cooler stars would be even more […]

Study Shows Dark Matter Dominates Nearby Dwarf Galaxy Triangulum II

Dark Matter Dominates in Nearby Dwarf Galaxy Triangulum II

A new study from the California Institute of Technology reveals that dwarf galaxy Triangulum II has the highest concentration of dark matter in any known galaxy. Dark matter is called “dark” for a good reason. Although they outweigh particles of regular matter by more than a factor of 5, particles of dark matter are elusive. […]

MIT Chemists Create New Adaptable Metallic-Cage Gels

MIT Chemists Create a New Type of Gel

By combining the flexibility of polymer gels with the rigid structure provided by metal-based clusters, chemists from MIT have created a new material that could be well-suited for a range of possible functions, including drug release, gas storage, or water filtration. These new gels, known as polyMOCs, are a hybrid of two materials called metallogels […]

Temperature of Ancient Seas May Shape Global Climate

Temperature of Ancient Seas Shape Global Climate

In a newly published study, scientists from Yale University detail the differences in ocean temperatures over the last 5 million years by creating a historical record for sea temperature gradients and comparing it with state-of-the-art climate model simulations. The study is published in the journal Nature Geoscience. Sea temperature gradients (contrasts) in the tropics and […]

VISTA Survey Telescope Discovers Massive Galaxies in the Early Universe

Astronomers Discover Massive Galaxies in the Early Universe

Using ESO’s VISTA Survey Telescope, astronomers have discovered a horde of previously hidden massive galaxies that existed when the Universe was in its infancy. The discovery has allowed astronomers reveal exactly when such massive galaxies first appeared. Just counting the number of galaxies in a patch of sky provides a way to test astronomers’ theories […]

NASA’s Solar Dynamics Observatory Sees Brightening Magnetic Loops

Solar Dynamics Observatory Sees Brightening Magnetic Loops

This short video from NASA’s Solar Dynamics Observatory shows arches of bundled magnetic loops sprouting from active regions on the Sun. Two active regions sprouted arches of bundled magnetic loops in this video from NASA’s Solar Dynamics Observatory taken on November 11-12, 2015. Charged particles spin along the magnetic field, tracing out bright lines as […]

Neuroscientists Identify New Mechanism That Contributes to Strengthening Synapses

Newly Identified Mechanism Helps Strengthen Links between Neurons

Neuroscientists from MIT have identified a new mechanism that allows the brain to strengthen links between neurons. When the brain forms memories or learns a new task, it encodes the new information by tuning connections between neurons. MIT neuroscientists have discovered a novel mechanism that contributes to the strengthening of these connections, also called synapses. […]

Astronomers Discover 5,400 mph Winds on Exoplanet HD 189733b

Exoplanet HD 189733b Has 5,400 mph Winds

New research from the University of Warwick reveals that exoplanet HD 189733b has winds of over 5,400 mph blowing from its day side to its night side. The University of Warwick discovery is the first time that a weather system on a planet outside of Earth’s solar system has been directly measured and mapped. The […]

NuSTAR Reveals the Active Galactic Nucleus of a Quasar

Researchers Reveal the Active Galactic Nucleus of a Quasar

Using data from the NuSTAR X-ray satellite, a team of astronomers has found that the emission from quasar 3C 273 most likely arises from two components: an accretion disk around the black hole and very rapidly moving charged particles in a jet. 3C 273 is the nearest high-luminosity quasar to Earth, about two billion light-years […]

‘Chemical Laptop’ Could Be Used to Search for Life Beyond Earth

Miniaturized Laboratory Computer Could Search for Signs of Life Outside Earth

Scientists have developed a miniaturized laboratory, called Chemical Laptop, that could be used to search for signs of life outside Earth. If you were looking for the signatures of life on another world, you would want to take something small and portable with you. That’s the philosophy behind the “Chemical Laptop” being developed at NASA’s […]

Rice Engineers Develop Light-Driven Nanosubmarines

Rice Develops Light-Driven Nanosubmarines

Scientists at Rice University have created single-molecule submersibles that contain just 244 atoms and are powered by ultraviolet light. Though they’re not quite ready for boarding a lá “Fantastic Voyage,” nanoscale submarines created at Rice University are proving themselves seaworthy. Each of the single-molecule, 244-atom submersibles built in the Rice lab of chemist James Tour […]

How Genetic Defects in Myelin Formation Cause White Matter Diseases

Yale Researchers Show How a Mutated Gene Wreaks Havoc on White Matter

New research from Yale University may shed insight into mechanisms to control the course of multiple sclerosis. Their results point to a role for FAM126A in supporting myelination, an important process in development and also following acute exacerbations in multiple sclerosis. An inherited disease of myelin marked by slow, progressive neurological impairment is caused by […]
