☆ ‘Sleeping giant’ massive black hole found in the Milky Way galaxy

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.

☆ Use It or Lose It? Mouse Study Reveals Key to Healthy Erections

By Ernie Mundell HealthDay ReporterHealthDayFRIDAY, Feb. 9, 2024 (HealthDay News) -- Is 'practice makes perfect' true for the male erection, too? The key seemed to lie in connective tissue cells called fibroblasts. So, "an increased frequency of erections leads to more fibroblasts that enable erection," he said. The opposite also appeared to be true: "A decreased frequency results in fewer of these cells," Göritz said. "This is not something we have shown in our study, so it is a bit speculative, but a reasonable interpretation is that it gets easier if you have regular erections,” Göritz said.

When it comes to exercise, there’s a difference between what’s ideal and what’s, well, possible. Maybe in a perfect world, you’d devote an hour a day to fitness, a finely tuned program of strength training and cardio. Focus on strength training. Jessie Mundell, a fitness trainer in Ontario, said she prioritizes resistance training when time is short. “Strength training is so effective at elevating the heart rate, and then bringing it down a bit during rest periods, and then back up again,” she said.

☆ The Euclid space telescope's first images show distant, hidden, and irregular galaxies that could help solve 2 of astronomy's grandest mysteries

The Euclid space telescope returned its first photos and they're stunning. Scientists said they hope to use data from Euclid to better understand dark matter and dark energy. AdvertisementAdvertisementThe Euclid space telescope, which launched in July, has a very important task ahead of it: produce the largest 3D map of the universe to help solve two of astronomy's grandest mysteries: What is dark energy? The other 95% is made of dark matter and dark energy. Astronomers can only observe the effect dark matter and dark energy have on regular matter.

☆ Star-filled Euclid images spur mission to probe 'dark universe'

PARIS, Nov 7 (Reuters) - European astronomers on Tuesday released the first images from the newly launched Euclid space telescope, designed to unlock the secrets of dark matter and dark energy - hidden forces thought to make up 95% of the universe. Scientists believe vast, seemingly organised structures such as Perseus could only have formed if dark matter exists. "The rest of the universe we call dark because it doesn't produce light in the normal electromagnetic spectrum. Tell-tale signs of the hidden force exerted by dark matter include galaxies rotating more quickly than scientists would expect from the amount of visible matter that can be detected. We think there's lots of dark matter in that cluster and pulling these galaxies together," she added.

☆ Euclid Telescope Dazzles With Detailed First Images of Our Universe

“And it’s those ingredients pulled together that is going to make Euclid the iconic cosmology mission of the day.”Whereas NASA’s James Webb Space Telescope zooms in on one part of the sky at a time, Euclid excels at imaging wide, but still detailed, swaths of the universe. That’s perfect for “when you want to look for a needle in a haystack,” Dr. Seiffert said, including objects like free-floating worlds. With the data Euclid sends home, researchers can learn about how the web of dark matter cementing our universe together influences the shapes and motions of visible objects in space. The telescope’s detailed resolution is also expected to help scientists map the distribution of galaxies across cosmic time, aiding in understanding dark energy, the inexplicable force pulling the universe apart. Over the summer, scientists worked around the clock to fix a faulty navigation sensor that made Euclid create images of winding star trails as the telescope tried to capture a piece of sky.

CAPE CANAVERAL, Fla. (AP) — Scientists on Tuesday unveiled the first pictures taken by the European space telescope Euclid, a shimmering and stunning collection of galaxies too numerous to count. The photos were revealed by the European Space Agency, four months after the telescope launched from Cape Canaveral. Although these celestial landscapes have been observed before by the Hubble Space Telescope and others, Euclid's snapshots provide "razor-sharp astronomical images across such a large patch of the sky, and looking so far into the distant universe," the agency said. In one picture, Euclid captured a group shot of 1,000 galaxies in a cluster 240 million light-years away, against a backdrop of more than 100,000 galaxies billions of light-years away. Although the Hubble Space Telescope previously observed the heart of this galaxy, Euclid’s shot reveals star formation across the entire region, scientists said.

☆ Euclid telescope’s first images reveal new cosmic details

What Euclid’s first images revealEuclid focused on an array of targets for its first scientific images. While dark matter has never actually been detected, it is believed to make up 85% of the total matter in the universe. Both dark matter and dark energy also play a role in the distribution and movement of objects, such as galaxies and stars, across the cosmos. These observations will effectively allow Euclid to see how the universe has evolved over the past 10 billion years. “Euclid will make a leap in our understanding of the cosmos as a whole, and these exquisite Euclid images show that the mission is ready to help answer one of the greatest mysteries of modern physics,” said Carole Mundell, ESA Director of Science, in a statement.

A SpaceX Falcon 9 rocket, with the European Space Agency Euclid space telescope, lifts off from pad 40 at the Cape Canaveral Space Force Station in Cape Canaveral, Fla., Saturday, July 1, 2023. The Euclid mission is designed to explore the evolution of the dark universe. A European space telescope blasted off Saturday on a quest to explore the mysterious and invisible realm known as the dark universe. SpaceX launched the European Space Agency's Euclid observatory toward its ultimate destination 1 million miles (1.5 million kilometers) away, the Webb Space Telescope's neighborhood. "It's more than a space telescope, Euclid.
