CNN —As darkness envelops millions of people during Monday’s total solar eclipse, spectators will hold their cellphones skyward to capture the moment. A family looks through a pair of giant solar eclipse glasses at Veterans Memorial Park in Dripping Springs, Texas, on April 4, 2024. When the last total solar eclipse cut a path across America in 2017, AT&T reported network usage spikes up to 15% around certain cell towers in the path of totality. People view the solar eclipse at 'Top of the Rock' observatory at Rockefeller Center, August 21, 2017 in New York City. “A total eclipse of the sun is unlike any other experience that a human being can have.

☆ How to see the eclipse: Why your path of totality maps might be slightly off
▼ + stars: | 2024-04-05 | by ( Jackie Wattles | ) edition.cnn.com time to read: +5 min

“Calculations that use a slightly larger radius for the size of the Sun yield an eclipse path that is slightly narrower,” said NASA spokesperson Karen Fox in an emailed statement. And even if the NASA map is wrong, Irwin’s calculations indicate it’s only off by a couple thousand feet on the edges. A woman views a map showing the eclipse path during the Solar Eclipse Festival at the California Science Center in Los Angeles, California, on August 19, 2017, two days before the total eclipse on August 21. And NASA also acknowledges that exact measurements of the eclipse path are difficult to pin down. “When you see the total eclipse, you can’t go back,” Guinan said.

☆ NASA's James Webb telescope spotted a strange 13 billion-year-old galaxy that shouldn't exist

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.

☆ Universe’s brightest known object and fastest-growing black hole revealed

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.

☆ Webb telescope spies millions of stars in stunning spiral galaxies

CNN —The James Webb Space Telescope has captured scintillating portraits of 19 spiral galaxies — and the millions of stars that call them home — in unprecedented detail never seen before by astronomers. Astronomers believe that about 60% of all galaxies are spiral galaxies — and our solar system resides in one of the spiral arms of the Milky Way galaxy. Webb’s observations can help astronomers better understand star formation and the evolution of spiral galaxies like our own. The James Webb Space Telescope captured images of 19 spiral galaxies in near- and mid-infrared light. The images will be used to help astronomers determine the distribution of gas and dust in spiral galaxies, as well as how galaxies both nurture and cease the formation of stars.

☆ Puzzlingly massive planet found orbiting a small star

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.

The individual moves the light source and with it, the two light points move, opposite each other, around the resin. The video does not prove that the sun and moon are reflections of another light source, or that the moon is a reflection of Earth. The moon is not a reflection of Earth.

CNN —The James Webb Space Telescope has looked into the heart of the Milky Way galaxy, unveiling new features and mysteries within the chaotic region that could help astronomers unravel more details about the early universe. Astronomers used Webb to glimpse Sagittarius C, or Sgr C, an active region of star formation located about 300 light-years from the galaxy’s central supermassive black hole Sagittarius A*. A light-year, equivalent to 5.88 trillion miles (9.46 trillion kilometers), is how far a beam of light travels in one year. Astronomers are still trying to determine what has created the vast amount of energized gas, which surpasses what would normally be released by young massive stars. “Webb has provided us with a ton of data on this extreme environment, and we are just starting to dig into it.”

Potential black hole theoryTypically, black holes located at the centers of galaxies only have about 0.1% the mass of the stars within their host galaxy. The unusual black hole could be an “Outsize Black Hole” that formed when a huge cloud of gas collapsed, as theorized in 2017 by Priyamvada Natarajan, a coauthor on both studies and the Joseph S. and Sophia S. Fruton professor of astronomy and professor of physics at Yale University in New Haven, Connecticut. “We think that this is the first detection of an ‘Outsize Black Hole’ and the best evidence yet obtained that some black holes form from massive clouds of gas,” Natarajan said.

The astronomers spied a high-speed jet stream in Jupiter’s lower stratosphere, an atmospheric layer about 25 miles (40 kilometers) above the clouds. “What we have always seen as blurred hazes in Jupiter’s atmosphere now appear as crisp features that we can track along with the planet’s fast rotation,” he said. Jet stream revelationsResearchers compared winds detected by Webb at high altitudes with those within the lower layers picked up by Hubble and tracked changes in wind speed. Both space observatories were necessary to detect the jet stream, as Webb spotted small cloud features and Hubble provided a look at the equatorial atmosphere, including storms not related to the jet. Future observations of Jupiter using the Webb telescope may uncover more insights into the jet stream, such as whether its speed and altitude shift over time, as well as other surprises.

The findings are “extremely exciting and unexpected, especially since Neptune’s previous period of low cloud activity was not nearly as dramatic and prolonged,” Chavez added. The findings also contradict the idea of the clouds being affected by Neptune’s four seasons, which each last about 40 years. Additionally, Neptune storms rising from the deep atmosphere do influence the planet’s cloud cover — but aren’t related to clouds formed in the upper atmosphere. That variable could interfere with studies looking at correlations between photochemically produced clouds and the solar cycle. More research could also suggest how long the near absence of clouds on Neptune might last.
