Using NASA’s Swift spacecraft, an international team of astronomers have performed X-ray observations of a classical nova named Nova Scorpii 2023. Results of the observational campaign, published October 21 on the pre-print server arXiv, deliver important insights into the properties and behavior of this eruption. Go to Source Using NASA’s Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers have detected a new exoplanet orbiting a bright K-type star known as TOI-283. The newfound alien world, which received the designation TOI-283 b, is about 40% smaller than Neptune. The discovery was detailed in a research paper published October 16 on the pre-print […] Every year, the Taurid meteor shower lights up the night sky from late October through early November. Sometimes called the “Halloween fireballs,” they are named for the constellation Taurus—the bull—from which the meteors appear to radiate. The shower is best viewed from dark-sky locations. Go to Source China said Thursday it’s on track to land astronauts on the moon by 2030 as it introduced the next crew of astronauts who will head to its space station as part of the country’s ambitious plans to be a leader in space exploration. Go to Source Our moon—or la Luna—has inspired humankind for millennia. Go to Source The Milky Way is a rich and complex environment. We see it as a luminous line stretching across the night sky, composed of innumerable stars. Go to Source The Habitable Worlds Observatory (HWO) is slated to be the next Great Observatory for the world. Its main focus has been searching for biosignatures in the atmospheres of at least 25 Earth-like exoplanets. However, to do that, it will require a significant amount of effort with only a coronagraph, the currently planned primary instrument, no […] A new study into how spaceflight impacts the human brain and eyes revealed notable sex differences in brain fluid shifts, with female astronauts showing a greater reduction in fluid around the uppermost part of the brain than their male counterparts. Go to Source A new analysis of chemical signatures measured by NASA’s Curiosity Rover gives a peek at Mars’s past to a time some 3.7 billion years ago, when it was warmer and wetter. Go to Source Mars is an inhospitable desert planet. Billions of years ago, things were different. In Jezero Crater, for example, fed by a vast river delta, there was probably a considerable body of water roughly the size of Lake Constance. Conditions conducive to life may have prevailed there. Go to Source For the first time, scientists have the calculations and simulations to explain mysterious flashes from the galaxy OJ 287. Roughly twice every 12 years, from 3.5 billion light years away, the light equivalent of 1 trillion suns flashes in the night sky and then fades away over the next few months. It’s a phenomenon that […] The European Space Agency’s upcoming Henon mission will be the first ever CubeSat to independently venture into deep space, communicate with Earth and maneuver to its final destination without relying on a bigger spacecraft. Once in its orbit around the sun, the carry-on luggage-sized CubeSat will observe the sun’s emissions to demonstrate technologies capable of […] New research conducted by an international team of physicians has found that high-energy gamma rays might offer the key to unlocking the mysteries of the sun’s magnetic fields. Go to Source Astronomers from the International Centre of Radio Astronomy Research (ICRAR) have created the largest low-frequency radio color image of the Milky Way ever assembled. This spectacular new image captures the Southern Hemisphere view of our Milky Way galaxy, revealing it across a wide range of radio wavelengths, the colors of radio light. Go to Source […] This new NASA/ESA/CSA James Webb Space Telescope Picture of the Month features a cosmic creepy-crawly called NGC 6537—the Red Spider Nebula. Using its Near-InfraRed Camera (NIRCam), Webb has revealed never-before-seen details in this picturesque planetary nebula with a rich backdrop of thousands of stars. Go to Source |
