First, one of the crew found a marble head of a Roman lady, and two weeks later its bust surfaced nearby, reuniting the pieces. Cambridge Archaeological UnitMust Farm was a thriving Bronze Age stilt village, perched above a river in eastern England, when it burned down 2,850 years ago — just nine months after its inhabitants had built it. The site, acclaimed by experts as “Britain’s Pompeii,” preserved rare information that reveals a new, less hierarchical portrait of Bronze Age society. Malhan/MPIAAstronomers have spied two streams of ancient stars that likely helped build the Milky Way galaxy billions of years ago. They find wonder in planets beyond our solar system and discoveries from the ancient world.

CNN —Astronomers using the James Webb Space Telescope have detected commonplace chemical ingredients found in vinegar, ant stings and even margaritas around two young stars, according to NASA. The complex organic molecules they observed using the space observatory’s Mid-Infrared Instrument included acetic acid, a component of vinegar, and ethanol — otherwise known as alcohol. The team also found simple molecules of formic acid, which causes the burning sensation associated with ant stings, as well as sulfur dioxide, methane and formaldehyde. Stars form from swirling clouds of gas and dust, and the leftover material from star formation gives rise to planets. Detecting complex organic molecules in space is helping astronomers to determine the molecules’ origins as well as those of other larger cosmic molecules.

☆ Webb space telescope spots oldest ‘dead’ galaxy
▼ + stars: | 2024-03-06 | by ( Ashley Strickland | ) edition.cnn.com time to read: +4 min

CNN —Astronomers have spotted the oldest “dead” galaxy ever observed while studying the cosmos with the James Webb Space Telescope, and it’s one of the deepest views into the distant universe made with the observatory to date. The galaxy existed when the universe was only about 700 million years into its current age of about 13.8 billion years. But something made the galaxy suddenly halt star formation almost as quickly as star birth had begun more than 13 billion years ago, and the researchers have yet to uncover the cause. Studying the galaxy could reveal new insights about the early universe and the factors that affect star formation within galaxies, according to the authors. “Until now, to understand the early universe, we’ve used models based on the modern universe.

In the future, the tiny satellite will be named after a Shakespearean character, in keeping with the tradition of Uranus’ moons bearing literary names. He worked with Marina Brozovic and Bob Jacobson of NASA’s Jet Propulsion Laboratory in Pasadena, California, to determine the moon’s orbit.

NASA's new space telescope spotted a 13 billion-year-old galaxy that is much too complex to exist that early in the universe. The galaxy, which is bigger than the Milky Way, could upheave what we know about how dark matter shaped the early universe. Light travels at a fixed speed through space, so the image of these early galaxies in the past is only reaching us now. According to current cosmology models, that should not be possible because dark matter is not supposed to have been mature enough at that time. "This dark matter — we don't know what it actually is —started out really smooth, with only the tiniest of ripples.

☆ White dwarf star has metal scar after gobbling planetary fragment
▼ + stars: | 2024-02-26 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —Astronomers have spotted an unusual sign that a dead star feasted on a fragment of a planet orbiting it: a metal scar on the star’s surface. The observation revealed a metallic feature on the star’s surface that the researchers determined was related to a change detected in the star’s magnetic field. The strength of the metal detection also synced with changes observed in the star’s magnetic field, which led the team to determine that the metal scar was located on one of the star’s magnetic poles. The star’s magnetic field pulled the metals toward the star, which led to the presence of the scar, the finding has suggested. But WD 0816-310 presents an entirely different scenario orchestrated by the star’s magnetic field.

CNN —Astronomers have spotted the brightest known object in the universe, and it’s a quasar powered by the fastest-growing black hole on record, according to a new study. The black hole powering the quasar devours the equivalent of one sun per day and has a mass about 17 billion times that of our sun, the researchers found. A black hole is massive power sourceThe intense gravitational influence of black holes draws matter toward these celestial objects in such an energetic way that the process creates light. The blinding radiation is due to the black hole’s accretion disk, or the ring around the black hole where material gathers before being consumed. The team followed up with observations from the powerful Very Large Telescope in Chile’s Atacama Desert to confirm details about the black hole, including its hefty mass.
