This dramatic scene captured by NASA’s James Webb Space Telescope looks like a fantastical tableau from J. R. R. Tolkien’s The Lord of the Rings. But truth is even stranger than fiction. In reality, what appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being sculpted by the […] One of the most difficult parts of astronomy is understanding how time affects it. The farther away you look in the universe, the farther back you look in time. One way this complicates things is how objects might change over time. For example, a supermassive black hole at the center of a galaxy in the […] A new systematic study of the atmospheric conditions at the Muztagh Station in western China has revealed the site’s unique suitability for optical observations. Researchers from the Xinjiang Astronomical Observatory of the Chinese Academy of Sciences reported that the location offers excellent “seeing” conditions, making it ideal for high-precision optical observations. The findings were published […] As Earth moves through space, it wobbles slightly. A team of researchers from the Technical University of Munich (TUM) and the University of Bonn has now succeeded in measuring these fluctuations in Earth’s axis using a completely new method—until now, possible only through complex radio astronomy. The team used the high-precision ring laser at TUM’s […] Researchers from the University of California San Diego Sanford Stem Cell Institute have discovered that spaceflight accelerates the aging of human hematopoietic stem and progenitor cells (HSPCs), which are vital for blood and immune system health. Go to Source The second of the Meteosat Third Generation Imagers, MTG-I2, has passed some important milestones in the cleanroom facilities at Thales Alenia Space in Cannes, southern France. Go to Source A research team has used both archival Hubble Space Telescope data and new observations to precisely measure the binary star system NGC3603-A1. One star weighs about 93 times the mass of our sun, while its companion tips the scales at roughly 70 solar masses. Together, they represent one of the most massive binary systems ever […] For this new Picture of the Month feature, the NASA/ESA/CSA James Webb Space Telescope has provided a fantastic new view of IRAS 04302+2247, a planet-forming disk located about 525 light-years away in a dark cloud within the Taurus star-forming region. With Webb, researchers can study the properties and growth of dust grains within protoplanetary disks […] At first glance, Saturn’s moon Enceladus seems rather unremarkable: it is much smaller than the Earth’s moon and is far away and completely covered in ice. Go to Source An international team of researchers has announced a significant advancement in gravitational-wave astronomy, with the detection of 128 new cosmic collisions involving black holes and neutron stars. Go to Source A study led by Jenny Frediani at Stockholm University has revealed a planet-forming disk with a strikingly unusual chemical composition: an unexpectedly high abundance of carbon dioxide (CO2) in regions where Earth-like planets may one day form. Go to Source The sun will someday die. This will happen when it runs out of hydrogen fuel in its core and can no longer produce energy through nuclear fusion as it does now. The death of the sun is often thought of as the end of the solar system. But in reality, it may be the beginning […] Every once in a while, you may look up toward the sun and see strange bright lights on either side of it. Or perhaps you’ll be sitting in an aircraft, looking out the window at its shadow, and see a circle of light, like a halo below (known as glories). Or, if you’re really adventurous, […] A team led by Prof. Mao Jirong from the Yunnan Observatories of the Chinese Academy of Sciences, in collaboration with international researchers, has recently published a study in The Astrophysical Journal confirming the presence of a standing shock in low-angular-momentum black hole accretion modes. Go to Source In Tenerife, Spain, stands a unique duo: ESA’s Izaña-1 and Izaña-2 laser-ranging stations. Together, they form an optical technology testbed of the European Space Agency that takes the monitoring of space debris and satellites to a new level while maturing new technologies for commercialization.
