A new super-Earth detected orbiting a red dwarf star

Fri, 2021-04-16 05:00
(Instituto de Astrofísica de Canarias (IAC)) In recent years there has been an exhaustive study of red dwarf stars to find exoplanets in orbit around them. These stars have effective surface temperatures between 2400 and 3700 K (over 2000 degrees cooler than the Sun), and masses between 0.08 and 0.45 solar masses.

Surprise twist suggests stars grow competitively

Fri, 2021-04-16 05:00
(National Institutes of Natural Sciences) A survey of star formation activity in the Orion Nebula Cluster found similar mass distributions for newborn stars and dense gas cores, which may evolve into stars. Counterintuitively, this means that the amount of gas a core accretes as it develops, and not the initial mass of the core, is the key factor in deciding the final mass of the produced star.

Fast radio bursts shown to include lower frequency radio waves than previously detected

Fri, 2021-04-16 05:00
(McGill University) A team led by McGill University researchers and members of Canada's CHIME Fast Radio Burst collaboration has established that fast radio bursts (FRBs) include radio waves at frequencies lower than ever detected before, a discovery that redraws the boundaries for theoretical astrophysicists trying to put their finger on the source of FRBs.

$50 million for WA to process signals from the dawn of time

Thu, 2021-04-15 05:00
(International Centre for Radio Astronomy Research) The Australian Federal Government will invest $64.4 million to establish a centre in Western Australia to process and analyse data from the SKA radio telescope. Each year, around 600 petabytes of SKA data will be stored for astronomers and astrophysicists from all over the world to access and analyse. The funding to establish a facility in Perth is part of $295 million announced this week.

Measuring neutron star squeezability

Thu, 2021-04-15 05:00
(American Physical Society) A team of scientists used a telescope on the International Space Station to measure the size of PSR J0740+6620 (J0740, for short), the most massive known neutron star. NASA's Neutron star Interior Composition Explorer (NICER) has captured unprecedented detail from this stellar remnant to learn more about matter in its core, which is on the threshold of collapsing into a black hole.

New NASA visualization probes the light-bending dance of binary black holes

Thu, 2021-04-15 05:00
(NASA/Goddard Space Flight Center) A pair of orbiting black holes millions of times the Sun's mass perform a hypnotic pas de deux in a new NASA visualization. The movie traces how the black holes distort and redirect light emanating from the maelstrom of hot gas - called an accretion disk - that surrounds each one.

Interspecifics awarded SETI x AI residency at SETI Institute and Ars Electronica Futurelab

Thu, 2021-04-15 05:00
(SETI Institute) The SETI Institute and the Ars Electronica Futurelab are announcing that Interspecifics, an independent artistic research studio founded in Mexico City, are the winners of the AI Lab residency, SETI x AI. The goal is to conceptualize and simulate life-like, self-organizing autonomous organisms that could provide insights into how life might originate in extraterrestrial habitats. They would manifest in both morphological and algorithmic forms. What might they look like in an AI setting fed by microbial intelligence? What would a computational symbiosis produce?

Baked meteorites yield clues to planetary atmospheres

Thu, 2021-04-15 05:00
(University of California - Santa Cruz) In a novel laboratory investigation of the initial atmospheres of Earth-like rocky planets, researchers at UC Santa Cruz heated pristine meteorite samples in a high-temperature furnace and analyzed the gases released. Their results suggest that the initial atmospheres of terrestrial planets may differ significantly from many of the common assumptions used in theoretical models of planetary atmospheres.

Fast-spinning black holes narrow the search for dark matter particles

Wed, 2021-04-14 05:00
(Massachusetts Institute of Technology) An MIT study narrows the search for particles called ultralight bosons, which, if they exist, could be an important component of dark matter. Certain ultralight bosons would be expected to put the brakes on the spin of black holes, but the new results show no such slowdown.
