Pressure Runs High At Edge Of Solar System

Out at the boundary of our solar system, pressure runs high. This pressure, the force plasma, magnetic fields and particles like ions, cosmic rays and electrons exert on one another when they flow and collide, was recently measured by scientists in totality for the first time -- and it was found to ...

Liquifying A Rocky Exoplanet

Rocky exoplanets that are around Earth-size are comparatively small, which makes them incredibly difficult to detect and characterise using telescopes.

Virtual 'Universe Machine' Sheds Light on Galaxy Evolution

How do galaxies such as our Milky Way come into existence? How do they grow and change over time? The science behind galaxy formation has remained a puzzle for decades, but a University of Arizona-led team of scientists is one step closer to finding answers thanks to supercomputer simulations.

Hubble Showcases New Portrait of Jupiter

The NASA/ESA Hubble Space Telescope reveals the intricate, detailed beauty of Jupiter's clouds in this new image taken on 27 June 2019 [1]. It features the planet's trademark Great Red Spot and a more intense color palette in the clouds swirling in the planet's turbulent atmosphere than seen in prev...

Dark Matter May Be Older than the Big Bang, Study Suggests

Dark matter, which researchers believe makeup about 80% of the universe's mass, is one of the most elusive mysteries in modern physics. What exactly it is and how it came to be is a mystery, but a new Johns Hopkins University study now suggests that dark matter may have existed before the Big Bang.

Magnetic Plasma Pulses Excited by UK-Size Swirls in the Solar Atmosphere

An international team of scientists led by the University of Sheffield has discovered previously undetected observational evidence of frequent energetic wave pulses the size of the UK, transporting energy from the solar surface to the higher solar atmosphere.

Methane Vanishing on Mars: Danish Researchers Propose New Mechanism as an Explanation

The processes behind the release and consumption of methane on Mars have been discussed since methane was measured for the first time for approx. 15 years ago. Now, an interdisciplinary research group from Aarhus University has proposed a previously overlooked physical-chemical process that can expl...

Researchers Decipher the History of Supermassive Black Holes in the Early Universe

Astrophysicists at Western University have found evidence for the direct formation of black holes that do not need to emerge from a star remnant. The production of black holes in the early universe, formed in this manner, may provide scientists with an explanation for the presence of extremely massi...

Smash and Grab: A Heavyweight Stellar Champion for Dying Stars

Dying stars that cast off their outer envelopes to form the beautiful yet enigmatic "planetary nebulae" (PNe) have a new heavy-weight champion, the innocuously named PNe "BMP1613-5406". Massive stars live fast and die young, exploding as powerful supernovae after only a few million years. However, t...
