Astronomers have detected large amounts of oxygen in the atmosphere of one of the oldest and most elementally depleted stars known. This finding provides an important clue on how oxygen was produced in the first generations of stars.
A NASA-supplied Atlas 5 rocket launched the European Space Agency’s Solar Orbiter spacecraft 9 February, kicking off an innovative mission to study the Sun in unprecedented detail, complementing close-in observations by NASA’s Parker Solar Probe.
During the day, a thin layer of nitrogen ice warms and turns into vapor. At night, the vapor condenses and once again forms ice. Each sequence is like a heartbeat, pumping nitrogen winds around the dwarf planet.
Spitzer has fundamentally changed astronomy textbooks. Recently the telescope batteries reached the end of their lives. The Spitzer team at NASA and the California Institute of Technology has no choice but to bid the spacecraft farewell.
SpaceX's launch of its next 60 Starlink satellites proceeded smoothly on Wednesday morning. About 1 hour after launch, the stack of satellites deployed into low-Earth orbit. The Falcon 9 rocket's thrice-used first stage landed on the drone ship.
The Daniel K. Inouye Solar Telescope (DKIST) recently took its first image which reveals an unprecedented level of details. These images provide a close-up view of the turbulent plasma arranged in a pattern of cell-like structures.
A NASA scientist analyzed the age of the Yarrabubba meteor crater in Australia and found it to be 2.229 billion years old, making it now the oldest crater currently known.
The star will go supernova at the end of its life, but that’s not projected to happen for tens of thousands of years or so. However, the great dimming of Betelgeuse continues.
A meteorite that crashed into Australia back in 1969 contains interstellar stardust dating back some 7 billion years, predating the formation of Earth by 2.5 billion years. The discovery offers a snapshot of the conditions that existed before our solar system.
The largest spiral galaxy in the local universe UGC 2885, is 2.5 times wider than the Milky way and hosts a trillion stars, 10 times more than Earth’s galactic home. UGC 2885 is located some 232 million light years away in the constellation Perseus.
The habitable-zone planet is one of three orbiting a star known as TOI 700, a cool M dwarf located about 100 light-years from Earth. The candidate planet, TOI 700 d, is is at a distance where temperatures would allow water to exist in liquid form.
This star is going to go nova (not supernova) by 2083. V Sagittae is in the constellation Sagitta and is s about 1100 light years from Earth. When the brightening happen, it will be historic. V Sge will appear startlingly bright in the night sky.
Astronomers have found six objects orbiting Sagittarius A* that are unlike anything in the galaxy. These objects look like gas but behave like stars. They are so peculiar that they have been assigned a brand-new class - what astronomers are calling G objects.
A team of astronomers has created the first global map of Titan by using the Cassini probe's over 100 fly-bys to stitch together both imagery and radar measurements.
Betelgeuse in constellation of Orion is looking markedly faint, the faintest it has been for the 21st century. Betelgeuse is a nearby supernova candidate. Its transformation into Type II supernova could occur 100,000 years from now… or tonight.
