It’s almost become expected that many space telescopes and probes can have “extended missions.” Both Voyagers are still sending data back 40+ years after their five-year primary mission ended. But figuring out what to do […]

Astronomers from Keele University in the UK have utilized NASA’s planet-hunting TESS telescope to investigate a totally-eclipsing binary known as UZ Draconis. Results of the new observations, published October 31 on the arXiv pre-print server, […]

Last week, four lasers were projected into the sky above the European Southern Observatory (ESO) Paranal site in Chile. The lasers successfully created an “artificial star” that astronomers can use to measure and then correct […]

Researchers at McGill University and collaborating institutions have mapped the atmospheric features of a planetary-mass brown dwarf, a type of space object that is neither a star nor a planet, existing in a category in-between. […]

Using the Five-hundred-meter Aperture Spherical Radio Telescope (FAST), astronomers from the Chinese Academy of Sciences (CAS) and elsewhere have observed a nearby pulsar known as PSR J2129+4119. Results of the observational campaign, published October 30 […]

An international team of astronomers has employed the James Webb Space Telescope (JWST) to observe a distant galaxy designated SXDF-NB1006-2. As a result, they found that SXDF-NB1006-2 is a young starburst galaxy that experiences ionized […]

The universe’s expansion may actually have started to slow rather than accelerating at an ever-increasing rate as previously thought, a new study suggests.This post was originally published on this site

This shimmering view of interstellar gas and dust was captured by the European Space Agency’s Euclid space telescope. The nebula is part of a so-called dark cloud, named LDN 1641. It sits at about 1,300 […]

Earth’s atmosphere is an impediment to astronomical observations. Not only is cloudy weather a problem, but temperature fluctuations in the atmosphere mean that ground-based telescopes require sophisticated adaptive optics systems to see clearly. Radio telescopes […]

The sun is governed by a strict rhythm. The magnetic activity of the sun displays a cyclic variation, reaching a maximum approximately every eleven years. Two enormous plasma circulations, each in one solar hemisphere, set […]
