Detecting the Neutrinos From a Supernova That’s About to Explode

Detecting the Neutrinos From a Supernova That’s About to Explode Neutrinos are puzzling things. They’re tiny particles, almost massless, with no electrical charge. They’re notoriously difficult to detect, too, and scientists have gone to great lengths to detect them. The IceCube Neutrino Observatory, for instance, tries to detect neutrinos with strings of detectors buried down […]

Finding NEMO: The future of gravitational-wave astronomy

Finding NEMO: The future of gravitational-wave astronomy A new study released today makes a compelling case for the development of “NEMO”—a new observatory in Australia that could deliver on some of the most exciting gravitational-wave science next-generation detectors have to offer, but at a fraction of the cost. phys.org Go to Source

Dawn Patrol: Jupiter and Saturn at Opposition 2020

Dawn Patrol: Jupiter and Saturn at Opposition 2020 Missing the planets in the first half of 2020? That’s all about to change, as the gas giants Jupiter and Saturn reach opposition in rapid succession this month, heralding a return to the dusk sky. The post Dawn Patrol: Jupiter and Saturn at Opposition 2020 appeared first […]

Study determines fundamental parameters of the chemically peculiar star HD 108662

Study determines fundamental parameters of the chemically peculiar star HD 108662 Astronomers have carried out a spectroscopic analysis of the atmosphere of a magnetic chemically peculiar star designated HD 108662. The study, described in a paper published June 29 on the arXiv preprint server, resulted in determining fundamental parameters of this star. phys.org Go to […]

Shock waves from stellar explosions take preferential direction

Shock waves from stellar explosions take preferential direction In a paper published in the Astrophysical Journal, a team led by researchers at École Polytechnique have paved the way to unraveling the mystery as to why many supernova remnants that we observe from Earth are axisymmetric (elongated along one axis) rather than spherical. phys.org Go to […]

A Tabletop-sized Experiment Could Help in the Search for Dark Matter

A Tabletop-sized Experiment Could Help in the Search for Dark Matter Dark matter is one of the least understood aspects in physics.  The evidence for dark matter is from its gravitational influence on galactic scales which cannot be explained by the presence of conventional matter.  Despite its large gravitational interactions, it is notoriously difficult to […]

The Corona Australis Molecular Cloud. Normally this Looks Like a Dark Blob in the Sky. But in Infrared, it Looks Like This.

The Corona Australis Molecular Cloud. Normally this Looks Like a Dark Blob in the Sky. But in Infrared, it Looks Like This. The Corona Australis is a constellation in the southern hemisphere. It’s name literally means “southern crown.” One of its features is the Corona Australis molecular cloud, home to a star-forming region containing young […]

The Moon Might Be More Metal-Rich Than We Thought

The Moon Might Be More Metal-Rich Than We Thought A new study shows that the Moon is more metal-rich than previously thought. That has some far-reaching implications for our understanding of the Moon’s formation. If their results are solid, it means that we may need to re-think the giant impact hypothesis for the formation of […]

Betelgeuse Probably Dimmed Because of Enormous Starspots

Betelgeuse Probably Dimmed Because of Enormous Starspots A few months ago we all watched as Betelgeuse dimmed. Between October 2019 and 22nd of February 2020 the star’s brightness dropped by a factor of about three. It went from magnitude 0.5, and from being the tenth-brightest star in the sky, to magnitude 1.7. Naturally, we all […]

The cosmic commute towards star and planet formation

The cosmic commute towards star and planet formation The molecular gas in galaxies is organized into a hierarchy of structures. The molecular material in giant molecular gas clouds travels along intricate networks of filamentary gas lanes towards the congested centers of gas and dust where it is compressed into stars and planets, much like the […]

NGC 2275: An Absolute Unit of Galactic Flocculence

NGC 2275: An Absolute Unit of Galactic Flocculence The Hubble Space Telescope has the knack for finding every size and shape of galaxy imaginable – from small, medium to large, all the way up to absolute units. This unusual galaxy, named NGC 2775, is incredibly fluffy-looking, or flocculent. It’s definitely a spiral, but instead of […]

Emission from the blazar 1ES 1218+304 explored with NASA space telescopes

Emission from the blazar 1ES 1218+304 explored with NASA space telescopes Using three NASA space observatories, astronomers have conducted a multiwavelength study of emission from a blazar known as 1ES 1218+304. Results of the investigation, presented in a paper published June 29 on arXiv.org, deliver more insights into the properties of this high-energy source. phys.org […]
