In an exciting and surprising scientific development, the James Webb Space Telescope has revealed information that could fundamentally change our understanding of the cosmos. In a recent press release, NASA announced that this state-of-the-art space instrument has detected evidence that the universe has stopped expanding, challenging previously accepted theories about the evolution of the universe. For decades, astronomers have been studying the expansion of the universe through observations of distant galaxies. The theory of cosmic expansion, supported by multiple lines of evidence, has been a fundamental basis of modern cosmology. However, data collected by the James Webb Space Telescope appear to contradict this widely accepted notion. According to scientists working on the project, observations from the telescope suggest that the universe is no longer expanding, but remains static or may even be undergoing a contraction. This unexpected finding raises a number of fundamental questions about the nature of the universe and its future destinies. Astronomers and cosmologists around the world are excited and perplexed by this discovery. This revelation is expected to generate intense research activity and scientific debate in the coming years, as scientists work hard to fully understand the implications of this new perspective.

This new NASA animation highlights the “super” in supermassive black holes. These monsters lurk in the centers of most big galaxies, including our own Milky Way, and contain between 100,000 and tens of billions of times more mass than our Sun. Any light crossing the event horizon – the black hole’s point of no return – becomes trapped forever, and any light passing close to it is redirected by the black hole’s intense gravity. Together, these effects produce a “shadow” about twice the size of the black hole’s actual event horizon. The animation shows 10 supersized black holes that occupy center stage in their host galaxies, including the Milky Way and M87, scaled by the sizes of their shadows. Starting near the Sun, the camera steadily pulls back to compare ever-larger black holes to different structures in our solar system. First up is 1601+3113, a dwarf galaxy hosting a black hole packed with the mass of 100,000 Suns. The matter is so compressed that even the black hole’s shadow is smaller than our Sun. The black hole at the heart of our own galaxy, called Sagittarius A* (pronounced ay-star), boasts the weight of 4.3 million Suns based on long-term tracking of stars in orbit around it. It’s shadow diameter spans about half that of Mercury’s orbit in our solar system. The animation shows two monster black holes in the galaxy known as NGC 7727. Located about 1,600 light-years apart, one weighs 6 million solar masses and the other more than 150 million Suns. Astronomers say the pair will merge within the next 250 million years. At the animation’s larger scale lies M87’s black hole, now with a updated mass of 5.4 billion Suns. Its shadow is so big that even a beam of light – traveling at 670 million mph (1 billion kph) – would take about two and a half days to cross it. The movie ends with TON 618, one of a handful of extremely distant and massive black holes for which astronomers have direct measurements. This behemoth contains more than 60 billion solar masses, and it boasts a shadow so large that a beam of light would take weeks to traverse it.

When NASA added a drone named Ingenuity to its Mars 2020 rover Perseverance, it expected the tiny four-pound helicopter to fly a total of five very brief missions in the thin Martian atmosphere. But Ingenuity far surpassed all expectations, flying dozens of flights before suffering damage to its rotors in January. Correspondent David Pogue reports on how the tiny drone, created from off-the-shelf parts, continued to provide valuable data and images from the Red Planet three years into its mission.

Our Milky Way galaxy is a swirling dance of hundreds of billions of stars, dust, and gas, all held together by gravity's invisible grip. This cosmic ballet plays out on a grand scale, with a central bulge at its heart and long, spiral arms stretching outwards. Within these arms, vast clouds of gas and dust collapse under their own weight, igniting new stars like fiery beacons. The galaxy isn't static, though. Stars zip around the center at incredible speeds, while the entire Milky Way slowly rotates. It's a delicate balance between the crush of gravity pulling inwards and the outward push from the galaxy's spin, creating a dynamic and ever-evolving celestial masterpiece.

During the week of May 10 to May 16, 2024, NASA’s Solar Dynamics Observatory (SDO) observed nine X-class solar flares erupting from the Sun, including the largest in this solar cycle to date on May 14 that peaked at X8.7. This video shows these flares using SDO observations in two wavelengths of extreme ultraviolet light, 131 angstroms (colorized as teal) and 171 angstroms (colorized as gold). These flares originated primarily from an active region on the Sun called AR 13664. This region, along with another called AR 13663, was responsible for the majority of strong solar flares from May 3 through May 9. A solar flare is an intense burst of radiation, or light, on the Sun. Flares are our solar system’s most powerful explosive events. Light only takes about eight minutes to travel from the Sun to Earth, so that’s how long it would take the energy from a flare to reach our planet. Solar flares are rated into different classes based on their strength, or energy output, and the effect a flare will have on Earth depends on what class it is (B, C, M, and X classes, with X being the most intense). Earth’s atmosphere absorbs most of the Sun’s intense radiation, so flares are not directly harmful to humans on the ground. However, energetic particles associated with flares can create a harmful radiation environment for astronauts, especially for human exploration activities beyond Earth’s protective magnetic field. Stronger solar flares — those rated class M5 or above — can have impacts on technology that depends on Earth’s ionosphere (our electrically charged upper atmosphere), like high-frequency radio used for navigation and GPS.

NASA works as a research arm of the nation’s space weather effort. NASA observes the Sun and our space environment constantly with a fleet of spacecraft that study everything from the Sun’s activity to the solar atmosphere, and to the particles and magnetic fields in the space surrounding Earth.

NASA’s PREFIRE mission aims to improve global climate change predictions by expanding our understanding of heat loss at the polar regions. The Polar Radiant Energy in the Far-InfraRed Experiment (PREFIRE) will send two shoebox-size satellites into space to study the Arctic and Antarctic. They’ll be the first to systematically measure heat in the form of far-infrared radiation emitted from those regions. Earth absorbs much of the Sun’s energy at the tropics. Weather and ocean currents then move that heat toward the poles, which help regulate Earth’s climate by radiating that heat back into space. But the Arctic is warming about three times faster than anywhere else on Earth, and that’s leading to increased ice sheet melt and sea level rise in coastal communities. The data from PREFIRE will help scientists better understand how Earth’s polar regions respond to climate change and what that might mean for the future.
