☆ Hubble image may contain evidence of stellar cannibalism in dumbbell-shaped nebula
▼ + stars: | 2024-04-25 | by ( Ashley Strickland | ) edition.cnn.com time to read: +4 min

The nebula, 3,400 light-years away in the Perseus constellation, is an expanding shell of gases kicked out by a dying red giant star. Before the aging red giant star collapsed, it released a ring of gas and dust. The companion star, once in orbit around the red giant, is nowhere to be seen in Hubble’s image. Since collapsing, the red giant star has transformed into a dead stellar remnant known as an ultra-dense white dwarf star. “The space telescope is the most scientifically productive space astrophysics mission in NASA history,” according to a NASA release.

Observations from the European Space Agency’s Cheops space telescope, or Characterising ExOplanet Satellite, detected a “glory effect” on WASP-76b, an ultra-hot exoplanet 637 light-years from Earth. Cheops captured data from WASP-76b as the planet passed in front of its star, making 23 observations over three years. But the glory effect is created as light moves through a narrow opening and bends, creating colorful, patterned rings. An artist's illustration shows the night-side view of the exoplanet WASP-76b, where iron rains down from the sky. Lueftinger said she believes that the James Webb Space Telescope or Ariel may be able to help prove the presence of the glory effect on WASP-76b.

☆ ‘Sleeping giant’ massive black hole found in the Milky Way galaxy
▼ + stars: | 2024-04-16 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —Astronomers have spotted the most massive known stellar black hole in the Milky Way galaxy after detecting an unusual wobble in space. The wobbling movement of an old giant star in the Aquila constellation revealed that it was in an orbital dance with a dormant black hole, and it’s the third such dormant black hole spotted by Gaia. So Gaia BH3 is the most massive black hole in our galaxy that formed from the death of a massive star. Stellar black holes observed across the Milky Way galaxy are about 10 times as massive as the sun on average. True to expectations, the researchers found that the star orbiting Gaia BH3 was metal-poor, which means that the star that formed Gaia BH3 was likely the same.

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.

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.

☆ 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.

The planet, about the mass of Neptune and more than 13 times as massive as Earth, was detected orbiting an ultracool M-dwarf star called LHS 3154 — which is nine times less massive than our sun. This graphic compares the sizes of our sun and Earth with the smaller, cooler LHS 3154 star and its orbiting planet, LHS 3154b. For example, small M dwarf stars are the most common throughout the Milky Way galaxy, and they typically have small, rocky planets orbiting them, rather than gas giant planets. “The planet-forming disk around the low-mass star LHS 3154 is not expected to have enough solid mass to make this planet,” Mahadevan said. A team of scientists led by Mahadevan built the HPF, which was designed to detect planets orbiting within the habitable zone of small, cool stars.

CAPE CANAVERAL, Fla. (AP) — Astronomers have discovered a rare in-sync solar system with six planets moving like a grand cosmic orchestra, untouched by outside forces since their birth billions of years ago. The find, announced Wednesday, can help explain how solar systems across the Milky Way galaxy came to be. The six found so far are roughly two to three times the size of Earth, but with densities closer to the gas giants in our own solar system. This solar system is unique because all six planets move similar to a perfectly synchronized symphony, scientists said. All solar systems, including our own, are thought to have started out like this one, according to the scientists.

☆ A Supernova ‘Destroyed’ Some of Earth’s Ozone for a Few Minutes in 2022

On Oct. 9, 2022, telescopes in space picked up a jet of high energy photons careening through the cosmos toward Earth, evidence of a supernova exploding 1.9 billion light-years away. Such events are known as gamma ray bursts, and astronomers who have continued studying this one said it was the “brightest of all time.”Now, a team of scientists have discovered that this burst caused a measurable change in the number of ionized particles found in Earth’s upper atmosphere, including ozone molecules, which readily absorb harmful solar radiation. “The ozone was partially depleted — was destroyed temporarily,” said Pietro Ubertini, an astronomer at the National Institute of Astrophysics in Rome who was involved in discovering the atmospheric event. The effect was detectable for just a few minutes before the ozone repaired itself, so it was “nothing serious,” Dr. Ubertini said. But had the supernova occurred closer to us, he said, “it would be a catastrophe.”The discovery, reported Tuesday in a paper published in the journal Nature Communications, demonstrates how even explosions that occur far from our solar system can influence the atmosphere, which can be used as a giant detector for extreme cosmic phenomena.
