This Ancient Pristine Galaxy Validates the Big Bang
If astronomers can find ancient, pristine galaxies with no metals, they will confirm our understanding of the Big Bang. Those galaxies have proven elusive, but a team of astronomers think they've found one. It may be the first Population 3 galaxy.
Gemini North Sees Brightening Interstellar Comet 3I/ATLAS in Detail
We’re getting better views of interstellar Comet 3I/ATLAS, as it makes its speedy passage through the inner solar system. This week, astronomers at the Gemini North observatory located on Mauna Kea in Hawai’i turned the facility’s enormous 8.1-meter telescope on the object, with amazing results.
A Rare Object Found Deep in the Kuiper Belt
Astronomers using the Subaru Telescope have discovered a new object in the Kuiper Belt, beyond the orbit of Pluto. Designated 2023 KQ14, it's categorized as a "sednoid," with an extremely eccentric orbit - only the 4th ever discovered. Its orbit is much different from other sednoids, which challenges the hypothesis that Planet Nine could be aligning their orbits. It was found at 72 AU, but its path takes it all the way out to 438 AU, taking almost 4,000 years to complete one orbit.
Watch the Moon Occult the Pleiades for North America on the Morning of July 20th
There’s a good reason for sky watchers to set their alarms this coming Sunday morning. If skies are clear, viewers across most of North America will have a rare chance to see the waning crescent Moon occult (pass in front of) the Pleiades open star cluster.
Student Led Mission Designs Highlight The Challenges Of Engineering In Space
There are plenty of engineering challenges facing space exploration missions, most of which are specific to their missions objectives. However, there are some that are more universal, especially regarding electronics. A new paper primarily written by a group of American students temporarily studying at Escuela Tecnica Superior de Ingenieria in Madrid, attempts to lay out plans to tackle several of those challenges for a variety of mission architectures.
A Star is Dissolving its Baby Planet
Astronomers have found a young star bathing a planet in intense X-ray radiation, wearing it away at a rapid rate. The planet is Jupiter-sized and orbits its red dwarf star at a fifth the distance from Mercury to the Sun. It's only 8 million years old, and researchers estimate that within a billion years, it will lose its entire atmosphere, going from 17 Earth masses down to just 2 Earth masses. They estimate that it's losing an Earth's atmosphere worth of mass every 200 years.
