How acids behave in ultracold interstellar space

Bochum-based researchers from the Cluster of Excellence Ruhr Explores Solvation (Resolv), together with cooperation partners from Nijmegen, have investigated how acids interact with water molecules at extremely low temperatures. Using spectroscopic analyses and computer simulations, they investigated the question of whether hydrochloric acid (HCl) does or does not release its proton in conditions like those found in interstellar space. The answer was neither yes nor…

RIT scientists recognized for solving issue with Landsat 8 satellite

Two Rochester Institute of Technology scientists were recognized by the U.S. Geospatial Intelligence Foundation as some of the tradecraft's brightest minds for their work on the Landsat 8 satellite. RIT senior scientists Aaron Gerace and Matthew Montanaro were presented with the USGIF Academic Achievement Award at the GEOINT 2019 Symposium in San Antonio, Texas, on June 4. Gerace and Montanaro received the award for their…

Mature galaxy mesmerizes in new Hubble view

IMAGE: NGC 7773 is a beautiful example of a barred spiral galaxy. A luminous bar-shaped structure cuts prominently through the galaxy's bright core, extending to the inner boundary of NGC 7773's... view more  Credit: ESA/Hubble & NASA, J. Walsh This striking image was taken by the NASA/ESA Hubble Space Telescope's Wide Field Camera 3 (WFC3), a powerful instrument installed on the telescope in 2009. WFC3 is…

Antarctic glacier named after GFZ satellite mission ‘GRACE’

A glacier in the West Antarctic has been named after the German-American satellite mission GRACE. GRACE stands for "Gravity Recovery and Climate Experiment". Between 2002 and 2017, the scientific mission measured the Earth's gravity field, from which conclusions can be drawn about the growth and melting of glaciers. The British Antarctic Survey has now published a map in which seven glaciers were named after satellite…

Fast and furious: detection of powerful winds driven by a supermassive...

The supermassive black holes in the centres of many galaxies seem to have a basic influence on their evolution. This happens during a phase in which the black hole is consuming the material of the galaxy in which it resides at a very high rate, growing in mass as it does so. During this phase we say that the galaxy has an active nucleus (AGN,…

NASA Opens International Space Station to New Commercial Opportunities, Private Astronauts

NASA is opening the International Space Station for commercial business so U.S. industry innovation and ingenuity can accelerate a thriving commercial economy in low-Earth orbit.

The mystery of the galaxy with no dark matter: Solved!

IMAGE: The ultra-diffuse galaxy KKS2000]04 (NGC1052-DF2), towards the constellation of Cetus, considered previously a galaxy with no dark matter.

Galaxies with no dark matter are impossible to understand in the framework of the current theory of galaxy formation, because the role of dark matter is fundamental in causing the collapse of the gas to form stars.…

Name an exoplanet

In recent years, astronomers have discovered thousands of planets and planetary systems orbiting around nearby stars. Some are small and rocky like the Earth, whilst others are gas giants like Jupiter. It is now believed that most stars in the Universe could have planets orbiting them and that some of them may have physical characteristics that resemble those of the Earth. The sheer number of…

The universal beauty of the mountains can be seen in graphs

Mountains have character. The continuous gentle, wavy hills and wide valleys of the Carpathians, Appalachians or lower parts of the Alps contrast strongly with the soaring peaks, ragged ridges and deep ravines of the high Tatra mountains and Pyrenees, which are, in turn, different from the inaccessible, snow-covered Himalayan or Andean giants, along whose slopes flow long tongues of glaciers instead of water. Beneath this…

Radio ridge between two galaxy clusters bridges intergalactic space

Intergalactic magnetic fields connect two merging galaxy clusters, according to a new study, which reports the first discovery of a vast ridge of radio-emitting plasma in a filament of the cosmic web. According to the authors, the results challenge current theories of particle acceleration in these vast regions of intergalactic space. Galaxy clusters - the most massive gravitationally bound structures in the Universe - can…
