Illustration shows how the star’s motion around the center of mass between it and the planet causes a “wobble” in its motion through space. The VLBA’s ability to detect this minuscule effect revealed the presence of the planet. Credit: Bill Saxton, NRAO/AUI/NSF Using the supersharp radio “vision” of the National […]

ANIMATION A study led by researchers at the Instituto de Astrofísica de Canarias (IAC), making comparison between the discs of several pairs of spiral galaxies, active and non-active, concludes that in the discs of the former the rotational motion of the stars is of greater importance. This study, just accepted […]

Molten lava in crucible placed under experimental setup. Setup includes a spectrometer (right) which measures the light from the lava at different wavelengths. Credit: Tajana Schneiderman By making their own lava and cooled glass, scientists find these materials likely aren’t responsible for the unexpected glow of some exoplanets. Arguably some […]

This artist’s illustration of Supernova 1987A shows the dusty inner regions of the exploded star’s remnants (red), in which a neutron star might be hiding. This inner region is contrasted with the outer shell (blue), where the energy from the supernova is colliding (green) with the envelope of gas ejected […]

The South Pole Telescope at the US Amundsen-Scott South Pole Station, with a bright aurora in July 2020. Credit: Geoff Chen Stars viewed from a place called Dome A in Antarctica can finally be seen without their twinkle – which means in much greater detail. Have you ever wondered why […]

HSC J1631+4426 broke the record for the lowest oxygen abundance. Credit: NAOJ/Kojima et al. Breaking the lowest oxygen abundance record. New results achieved by combining big data captured by the Subaru Telescope and the power of machine learning have discovered a galaxy with an extremely low oxygen abundance of 1.6% […]

An artist’s representation of the Phoenix Stellar Stream. Originally a ball of stars, known as a globular cluster, Phoenix has been stretched into a stream of stars by the gravitational pull of the Milky Way. In a few billion years, Phoenix will be completely destroyed and absorbed into our galaxy. […]

“The Elephant in the room” — Illustration of the experimental setup to search for hidden matter inside the Earth. Credit: Nataniel L. Figueroa Using a network of gravimeters, Mainz-based scientists are attempting to track down weakly interacting matter in the interior of the Earth. An interdisciplinary research team led by […]

Observation of a large solar flare on Sept. 10, 2017 in extreme ultraviolet (grayscale background, by NASA’s Solar Dynamics Observatory) and microwave (red to blue indicate increasing frequencies, observed by the Expanded Owens Valley Solar Array). Light orange curves are selected magnetic field lines from the matching theoretical solar eruptive […]
