Astronomers now estimate there is at least one planet for every star in our galaxy. These worlds, called exoplanets, are planets that orbit stars outside our solar system. But new research from McMaster University reveals a surprising twist: the most common planets in our galaxy don’t exist around the most common stars. Go to Source […] An international team of astronomers reports the discovery of a new supernova remnant (SNR) using radio observations. The newfound supernova remnant, dubbed Abeona, is one of the faintest radio SNRs so far detected. The discovery is detailed in a research paper published April 21 on the arXiv preprint server. Go to Source […] The spacecraft that flew four astronauts around the moon is back where its record-breaking journey began. Go to Source Shielding materials are essential in key modern industrial settings—such as spacecraft, nuclear power plants, semiconductor equipment, and advanced medical devices—to protect both equipment and personnel from electromagnetic waves and radiation. In particular, as space exploration gains momentum—such as with the successful launch of Artemis 2 on the 2nd—the importance of next-generation shielding technology capable of […] A technology that could propel crewed missions to Mars and robotic spacecraft throughout the solar system was recently put to the test at NASA’s Jet Propulsion Laboratory in Southern California. On Feb. 24, for the first time in years and at power levels exceeding any previous test in the United States, a team fired up […] The bright whites of mountain snow, muted browns of the arid plains, and gem-like blues and teals of glacial lakes typically dominate the Patagonian color palette. But for a short time in the austral autumn, temperate deciduous forests add splashes of warm tones. On April 12, 2026, a break in the clouds allowed the Landsat […] Understanding the universe as a whole requires simulations on cosmic scales. An international team of astrophysicists, with a leading role for researchers at Leiden University, Netherlands, has now released one of the largest cosmological simulation datasets ever produced. The dataset contains more than 2.5 petabytes of simulation data—roughly equivalent to half a million HD movies. […] An international team of astronomers has employed the Atacama Large Millimeter/submillimeter Array (ALMA) to perform high-resolution observations of the Needle galaxy. Results of the new observational campaign, presented April 15 on the arXiv preprint server, provide more insights into the properties of molecular gas in this galaxy. Go to Source NASA’s Curiosity and Perseverance rovers have captured two 360-degree landscapes that highlight how the missions are revealing details of the red planet’s formation, watery past, and potential for life. Located 2,345 miles (3,775 kilometers) apart from each other on Mars—about the distance from Los Angeles to Washington, D.C.—both rovers are exploring areas that are billions […] The moon has played a huge role in the development of Earth. It stabilizes the planet, tempers dramatic climate swings, and possibly even provides the tidal heating that might have led to the first life forms. So it’s natural we would want to find a similar Earth/Luna system somewhere else in the cosmos. But astronomers […] From birth to death, stars generally slow by 100 to 1,000 times their initial rotation rates; in other words, they “spin down.” The sun’s total angular momentum has declined as material is gradually blown off at the surface as solar wind. By observing this, astronomers have theorized the interaction between magnetic fields and plasma flow […] When Mauna Loa erupted in 2022, the largest lava flow headed on a path headed directly toward Daniel K. Inouye State Highway 200, also known as Saddle Road, a critical route that carries many residents from their homes on one side to their jobs on the other. Go to Source Astronomers can use telescopes to find specific molecules in the atmospheres of neighboring planets, in nebulae—clouds of interstellar dust and gas—hundreds or thousands of light-years away, or in galaxies beyond the far reaches of the Milky Way. Go to Source Planets may actually form more easily around double stars than around single stars like our sun, according to new research from astrophysicists at the University of Lancashire. Binary stars are common in our galaxy, yet for a long time astronomers believed that the gravitational tug-of-war between two stars would make it harder for circumbinary planets, […] I watched Armageddon again fairly recently with Bruce Willis, oil drillers in space and an asteroid the size of Texas bearing down on Earth. Buried beneath the Hollywood chaos is a genuinely interesting question: What exactly could we do with an asteroid if we got our hands on one? As it turns out, the answer […] |
