Study Suggests Andromeda Crashed into the Milky Way 10 Billion Years Ago

Andromeda Galaxy

A new study suggests that Andromeda crashed into the Milky Way roughly 10 billion years ago, explaining the observed structure of the two galaxies and their satellites. For many years scientists have believed that our Galaxy, the Milky Way, is set to crash into its larger neighbor, the Andromeda Galaxy, in about 3 billion years’ […]

Astronomers View Distant Galaxy Feeding on Nearby Gas

ESO Spots Distant Galaxy Feeding on Nearby Gas

Using two instruments known as SINFONI and UVES, astronomers were able to view a distant galaxy feeding on nearby gas, revealing how the galaxy itself was rotating, and revealing the composition and motion of the gas outside the galaxy. Astronomers using ESO’s Very Large Telescope have spotted a distant galaxy hungrily snacking on nearby gas. […]

Scientists Discover Surprising Amount of Dust and Gas in the Remnant of Supernova 1987A

Supernova 1987A Helps Explain Why Space is so Abundant with Dust Grains and Molecules

Using the Herschel Space Observatory and Atacama Millimeter and Submillimeter Array, researchers have discovered a vast reservoir of unexpectedly cold molecules and dust from the remnant of supernova 1987A. Surprisingly low temperatures detected in the remnant of the supernova 1987A may explain the mystery of why space is so abundant with dust grains and molecules. […]

Researchers Identify the P2Y2 Receptor Molecule as the Gateway for Metastases

Activated Blood Platelets Enable Cancer Cells to Penetrate Blood Vessels

Researchers from the Max Planck Institute have identified the P2Y2 receptor molecule on the cells of the blood platelet wall as the gateway that enables cancer cells to penetrate blood vessels and to enter the organs. Malignant tumors often spread to remote areas of the body. In the majority of cases, metastases formation develops via […]

ESA’s Cluster Spacecraft Detects Plasmaspheric Wind

Plasma Outflow from Plasmasphere to Magnetosphere

In a newly published study, researcher Iannis Dandouras details the discovery of plasmaspheric wind, providing the first conclusive proof of the existence this wind first proposed theoretically over 20 years ago. By analyzing data from the European Space Agency’s Cluster spacecraft, researcher Iannis Dandouras detected this plasmaspheric wind, so-called because it contributes to the loss […]

New Adaptive Optics System GeMS Delivers Sharper Images of the Universe

GeMS Delivers Sharper Images of the Universe

A new adaptive optics system, called GeMS, uses a combination of multiple lasers and deformable mirrors to remove atmospheric distortions from ground-based images, providing astronomers with ultrasharp data. Astronomers recently got their hands on Gemini Observatory’s revolutionary new adaptive optics system, called GeMS, “and the data are truly spectacular!” says Robert Blum, Deputy Director of […]

Red Dwarf Stars Could Leave Habitable Earth-Like Planets Vulnerable to Radiation

How Mars Lost Most of its Atmosphere

New research from scientists at the University of St Andrews investigates the effect of the magnetic fields of M dwarf stars on potentially habitable Earth-like planets, suggesting that the magnetic fields of red dwarfs leave any life vulnerable to radiation from space. Red dwarf stars are the commonest type of stars, making up about 75% […]
