Hubble Views Two Interacting Galaxies

Hubble Views Two Interacting Galaxies

This newly released Hubble image shows two interacting galaxies – NGC 6872 and IC 4970. This picture, taken by the NASA/ESA Hubble Space Telescope’s Wide Field Planetary Camera 2 (WFPC2), shows a galaxy known as NGC 6872 in the constellation of Pavo (The Peacock). Its unusual shape is caused by its interactions with the smaller […]

‘Hot Jupiters’ Can Force Their Host Stars to Wobble

Hot Jupiters Make Their Suns Wobble

A new study from Cornell University shows that when the “Hot Jupiters” approach their host star, the planet can force the star’s spin axis to precess much like a wobbling, spinning top. According to new Cornell research published in Science, these large, gaseous exoplanets can make their suns wobble after they wend their way through […]

Researchers Reset Human Pluripotent Stem Cells to a Fully Pristine State

Researchers Reset Human Pluripotent Stem Cells to a Fully Pristine State

A newly published study details how scientists were able to successfully ‘reset’ human pluripotent stem cells to a fully pristine state. Researchers at EMBL-EBI have resolved a long-standing challenge in stem cell biology by successfully ‘resetting’ human pluripotent stem cells to a fully pristine state, at the point of their greatest developmental potential. The study, […]

NASA’s IRIS Satellite Observes Large Solar Flare

Interface Region Imaging Spectrograph Satellite Observes Major Solar Flare

NASA’s Interface Region Imaging Spectrograph satellite observed its largest solar flare since launching in 2013 – an X1.6 class flare. On September 10, 2014, NASA’s IRIS satellite observed an X1.6 class flare based on the high intensity of X-ray radiation. “X-class” events are the most powerful, and this one comes on the heels of another […]

Astronomers Measure Molecular Emission and Dust Temperatures of the Pipe Nebula

The Pipe Nebula

Astronomers from the Harvard-Smithsonian Center for Astrophysics recently completed a study of the dense cores of the Pipe Nebula, revealing that the cores are very cold, between 13 and 19 kelvin, with the coldest ones containing the most obscuring dust. The Pipe Nebula is a prominent dark molecular cloud located about 430 light-years from us. […]

NASA’s Curiosity Rover Arrives at Mount Sharp

Curiosity Rover Arrives at Mount Sharp

After 2 years and roughly 9 kilometers of driving, NASA’s Mars Curiosity rover has arrived at the base of Mount Sharp to begin a new phase of exploration. NASA’s Mars Curiosity rover has reached the Red Planet’s Mount Sharp, a Mount-Rainier-size mountain at the center of the vast Gale Crater and the rover mission’s long-term […]

New Guidelines for the Search for Alien Life on Other Planets

Researchers Give Guideline for Future Alien Life Search

Using an altitude-dependent photochemical model with the enhanced lower boundary conditions necessary to carefully explore abiotic oxygen and ozone production on lifeless planets with a wide variety of volcanic gas fluxes and stellar energy distributions, scientists at NASA have developed new guidelines for the search for life on other planets. Astronomers searching the atmospheres of […]

High-Resolution Images Reveal Surface of Comet 67P/Churyumov-Gerasimenko

Surface Map of Comet 67P

High-Resolution images taken by OSIRIS reveal a detailed scientific description of the surface of comet 67P/Churyumov-Gerasimenko. High-resolution images of comet 67P/Churyumov-Gerasimenko reveal a unique, multifaceted world. ESA’s Rosetta spacecraft arrived at its destination about a month ago and is currently accompanying the comet as it progresses on its route toward the inner solar system. Scientists […]

Graphene Paint Makes Impermeable and Chemically Resistant Coatings

Graphene Paint Can Make Impermeable and Chemically Resistant Coatings

New research from the University of Manchester demonstrates how a thin layer of graphene paint can make impermeable and chemically resistant coatings, which could be used for packaging to keep food fresh for longer and protect metal structures against corrosion. The surface of graphene, a one atom thick sheet of carbon, can be randomly decorated […]

Kepler Data Helps Pinpoint ‘Venus Zone’ Around Stars

Astronomers Pinpoint Venus Zone Around Stars

Using data from the Kepler Space Telescope, astronomers have defined the inner and outer edges of the “Venus Zone” – the point at which a planet’s atmosphere would experience runaway greenhouse-gas effects like those seen on Venus. San Francisco State University astronomer Stephen Kane and a team of researchers presented today the definition of a […]

New Nanotechnology Aids in Electron Cooling Without External Sources

New Nanotechnology Aids in Cooling Electrons Without External Sources

Using a nanoscale structure that consisted of a sequential array of a source electrode, a quantum well, a tunneling barrier, a quantum dot, another tunneling barrier, and a drain electrode, researchers were able to suppress electron excitation and cool electrons to -228 °C without external means at room temperature. A team of researchers has discovered […]

Astronomers Solve Quasar Sequence Mystery

New Study Explains Mysterious Quasar Sequence

New research helps solves a quasar mystery that astronomers have been puzzling over for 20 years, presenting a pathway to a better understanding of how supermassive black holes accrete matter and interplay with their environments. Pasadena, California – Quasars are supermassive black holes that live at the center of distant massive galaxies. They shine as […]
