This map illustrates the X-ray view of the sky, as observed by the NASA's Neutron star Interior Composition Explorer (NICER), a scientific instrument on the International Space Station. NICER's main scientific objectives require that it track cosmic sources while the station completes an orbit around Earth every 93 minutes. The data within this map includes information gathered during the initial 22 months of NICER's scientific operations. Each arc traces X-rays, as well as occasional strikes from energetic particles, captured during NICER’s night moves. The brightness of each point in the image is a result of these contributions as well as the time NICER has spent looking in that direction. NICER’s primary mission is to determine the size of dense remains of dead stars called neutron stars — some of which we see as pulsars — to a precision of 5%. These measurements will finally allow physicists to solve the mystery of what form of matter exists in their incredibly compressed cores. Credits: NASA/NICER

James Webb Space Telescope's First Spectrum of a TRAPPIST-1 Planet: Tablizer shares a report from Space.com: In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star. Astronomers obtained new data from the James Webb Space Telescope (JWST) on TRAPPIST-1 b, the planet in the TRAPPIST-1 solar system closest to its star. These new observations offer insights into how its star can affect observations of exoplanets in the habitable zone of cool stars. In the habitable zone, liquid water can still exist on the orbiting planet's surface. The team, which included University of Michigan astronomer and NASA Sagan Fellow Ryan MacDonald, published its study in the journal The Astrophysical Journal Letters. "Our observations did not see signs of an atmosphere around TRAPPIST-1 b. This tells us the planet could be a bare rock, have clouds high in the atmosphere or have a very heavy molecule like carbon dioxide that makes the atmosphere too small to detect," MacDonald said. "But what we do see is that the star is absolutely the biggest effect dominating our observations, and this will do the exact same thing to other planets in the system.

https://buff.ly/3PZTx93 New research by scientists from NASA and Japan’s Osaka University suggests that rogue planets – worlds that drift through space untethered to a star – far outnumber planets that orbit stars. The results imply that NASA’s Nancy Grace Roman Space Telescope, set to launch by May 2027, could find a staggering 400 Earth-mass rogue worlds. Indeed, this new study has already identified one such candidate. “We estimate that our galaxy is home to 20 times more rogue planets than stars – trillions of worlds wandering alone,” said David Bennett, a senior research scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, and a co-author of two papers describing the results. “This is the first measurement of the number of rogue planets in the galaxy that is sensitive to planets less massive than Earth.” The team’s findings stem from a nine-year survey called MOA (Microlensing Observations in Astrophysics), conducted at the Mount John University Observatory in New Zealand. Microlensing events occur when an object such as a star or planet comes into near-perfect alignment with an unrelated background star from our vantage point. Because anything with mass warps the fabric of space-time, light from the distant star bends around the nearer object as it passes close by. The nearer object acts as a natural lens, creating a brief spike in the brightness of the background star’s light that gives astronomers clues about the intervening object that they can’t get any other way. “Microlensing is the only way we can find objects like low-mass free-floating planets and even primordial black holes,” said Takahiro Sumi, a professor at Osaka University, and lead author of the paper with a new estimate of our galaxy’s rogue planets. “It’s very exciting to use gravity to discover objects we could never hope to see directly.”

Five New Images from Europe's Euclid Space Telescope FriendsofNASA.org: The European Space Agency’s Euclid space mission has released five unprecedented new views of the Universe. These never-before-seen images demonstrate Euclid’s ability to unravel secrets of the cosmos. "Scientists are now equipped to hunt for rogue planets, to study mysterious matter through lensed galaxies, and explore the evolution of the Universe. Join us as we explore these groundbreaking discoveries and what they mean for the future of space exploration."

The Sombrero Galaxy in Infrared Credit: R. Kennicutt (Steward Obs.) et al., SSC, JPL, Caltech, NASA Explanation: This floating ring is the size of a galaxy. In fact, it is a galaxy -- or at least part of one: the photogenic Sombrero Galaxy, one of the largest galaxies in the nearby Virgo Cluster of Galaxies. The dark band of dust that obscures the mid-section of the Sombrero Galaxy in optical light actually glows brightly in infrared light. The featured image, digitally sharpened, shows the infrared glow, recently recorded by the orbiting Spitzer Space Telescope, superposed in false-color on an existing image taken by NASA's Hubble Space Telescope in visible light. The Sombrero Galaxy, also known as M104, spans about 50,000 light years across and lies 28 million light years away. M104 can be seen with a small telescope in the direction of the constellation Virgo. #PhoenixDelivers #nasa

The NASA/ESA/CSA James Webb Space Telescope has captured near- and mid-infrared portraits of 19 face-on spiral galaxies, providing unprecedented views of stars, gas, and dust on scales previously unseen beyond our own galaxy. These intricate portraits, showcasing the telescope's advanced capabilities, are part of the Physics at High Angular resolution in Nearby GalaxieS (PHANGS) program, inviting researchers to delve into the origins of these cosmic structures and deepen our understanding of star formation and spiral galaxy evolution. #infinitycosmos More Read > https://lnkd.in/giCbW--U

Black Hole Hubble Did you know Hubble helped verify that black holes exist? Since launching in 1990, it's helped astronomers learn lots about these cosmic objects. For example, this amazing view taken by Hubble Space Telescope in the 1990s show disks of dust fueling black holes at the centers of galaxies. Hubble taught us that black holes exist at the hearts of most galaxies. It also completed a census of galaxies, and showed that a black hole’s mass depends on the mass of its host galaxy’s central bulge of stars: the larger the galaxy, the larger the black hole.
