New cataclysmic variable discovered that may contain a brown dwarf secondary
An international team of astronomers reports the discovery of a new cataclysmic variable. The newfound system, designated SRGeJ041130.3+685350 (or SRGeJ0411 for short), has an orbital period of about 100 minutes and may contain a brown dwarf. The fin.....»»
The implications of "Oumuamua on the panspermia theory
On October 19, 2017, astronomers with the Pan-STARRS survey detected an interstellar object (ISO) passing through our solar system for the first time. The object, known as 1I/2017 U1 'Oumuamua, stimulated significant scientific debate and is still co.....»»
Gravitational waves could show us the first minute of the universe
Astronomers routinely explore the universe using different wavelengths of the electromagnetic spectrum from the familiar visible light to radio waves and infrared to gamma rays. There is a problem with studying the universe through the electromagneti.....»»
Why is the universe ripping itself apart? A new study shows dark energy may be more complicated than we thought
What is the universe made of? This question has driven astronomers for hundreds of years......»»
Earth"s Wobble Wreaks Havoc on Astronomers--And Astrologers, Too
Our planet’s precession is scarcely noticeable during anyone’s lifetime, but across history, it has had enormous effects.....»»
Astronomers discover extremely hot exoplanet with ‘lava hemisphere’
An Earth-sized orbits a star similar to our sun, but much, much closer - meaning it has surface temperatures of nearly 2,300 degrees Fahrenheit......»»

Astronomers find spark of star birth across billions of years
Astronomers have completed the largest and most detailed study of what triggers stars to form in the universe's biggest galaxies, using NASA's Chandra X-ray Observatory and other telescopes. They were surprised to find that the conditions for stellar.....»»
Webb discovers baffling ‘cat’s tail’ in Beta Pictoris
Astronomers using the James Webb Space Telescope have captured images of a dusty “cat’s tail” in the young planetary system known as Beta Pictoris. This … The post Webb discovers baffling ‘cat’s tail’ in Beta.....»»
Fermi Gamma-ray Space Telescope detects surprise gamma-ray feature beyond our galaxy
Astronomers analyzing 13 years of data from NASA's Fermi Gamma-ray Space Telescope have found an unexpected and as yet unexplained feature outside of our galaxy......»»
Astronomers found ultra-hot, Earth-sized exoplanet with a lava hemisphere
Also: A separate team found a small, cold exoplanet with a massive outer companion. Enlarge / Like Kepler-10 b, illustrated above, newly discovered exoplanet HD 63433 d is a small, rocky planet in a tight orbit of its star. (cre.....»»
Astronomers find direct link that supernovae give rise to black holes or neutron stars
Astronomers have found a direct link between the explosive deaths of massive stars and the formation of the most compact and enigmatic objects in the universe—black holes and neutron stars. With the help of the European Southern Observatory's Very.....»»
Jupiter has at least three magnetosheath jets, finds Voyager 2 data study
A team of astrophysicists and astronomers from Harbin Institute of Technology, Johns Hopkins University and Peking University has found evidence from Voyager 2 data showing that Jupiter has at least three magnetosheath jets. The study is published in.....»»
NGC 2403 XMM4 is a super-Eddington neutron star, study finds
By analyzing the data from various space telescopes, astronomers have performed a detailed study of an ultraluminous X-ray source known as NGC 2403 XMM4. Results of the study, published January 5 in the Monthly Notices of the Royal Astronomical Socie.....»»
Astronomers think they finally know origin of enormous “cosmic smoke rings“
Massive stars burn out quickly. When they die, they expel their gas as outflowing winds. Enlarge / Odd radio circles are large enough to contain galaxies in their centers and reach hundreds of thousands of light years across. (c.....»»
New large stellar flare detected from EV Lacertae
Astronomers have performed multiwavelength observations of a nearby M-dwarf star known as EV Lacertae (or EV Lac for short). The observational campaign resulted in the detection of a new large stellar flare from this object. The finding was detailed.....»»
Webb finds signs of possible aurorae on isolated brown dwarf
Astronomers using NASA's James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discov.....»»
Unexpectedly massive black holes dominate small galaxies in the distant universe
Astronomers have discovered that the supermassive black holes in the centers of early galaxies are much more massive than expected. These surprisingly hefty black holes offer new insights into the origins of all supermassive black holes, as well as t.....»»
When polar bears hunt snow geese, hunger justifies the means
Polar bears (Ursus maritimus) take advantage of the winter to build up their fat reserves. Intensive hunting of seals, a resource rich in fat, allows bears to store up enough energy to get through the summer......»»
