The evolving periodicity of the brightness of certain types of stars can now be described mathematically.
Scientists planning the Interstellar Probe mission, which will travel 1,000 AU from the sun, roughly 10 times as far as the Voyager spacecraft, will discuss the mission at the European Geosciences Union General Assembly 2021, which is taking place from 19-30 April 2021.
In celebration of the 31st anniversary of the launching of the NASA/ESA Hubble Space Telescope, astronomers aimed the celebrated observatory at one of the brightest stars seen in our galaxy to capture its beauty.
In celebration of the 31st anniversary of the launching of NASA's Hubble Space Telescope, astronomers aimed the renowned observatory at a brilliant "celebrity star," one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust.
A research team led by Dr. LI Leping from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC) proposed a new formation mechanism for coronal rain along open magnetic structures facilitated by interchange magnetic reconnection between open and closed magnetic structures.
Stars spin faster than expected as they age according to a new study led by scientists at the University of Birmingham which uses asteroseismology to shed new light on this emerging theory.
On May 1, 2019, researchers observed a record-setting flare from the star Proxima Centauri--a burst of energy roughly 100 times more powerful than any similar event seen from Earth's sun.
Scientists have found fragments of titanium blasting out of a famous supernova. This discovery, made with NASA's Chandra X-ray Observatory, could be a major step in pinpointing exactly how some giant stars explode.
Astronomers have discovered a pulsar--a dense and rapidly spinning neutron star sending radio waves into the cosmos--using a low-frequency radio telescope in outback Australia. The new pulsar is located more than 3,000 light-years from Earth and spins about once every second. Pulsars are used by astronomers for applications including testing the laws of physics under extreme conditions. The study of pulsars is one of the headline areas of science for the multi-billion-dollar Square Kilometre Array.
By studying ancient meteorite fragments, scientists can gain important insights into how our solar system formed eons ago. Now, in a new study, researchers have discovered carbon dioxide-rich liquid water inside a meteorite from an asteroid that formed 4.6 billion years ago. This finding suggests that the meteorite's parent asteroid formed beyond Jupiter's orbit before being transported into the inner solar system and provides key evidence for the dynamics of the Solar System's formation.
