1/13/2023 10:00 AMOnly two spacecraft have ever left our solar system and lived to tell the tale. In 2012 and 2019, NASA’s Voyager 1 and 2 spacecraft respectively broke through the heliopause, the boundary at which our sun’s sphere of influence gives way to the interstellar medium. They have sent back remarkable riches from this distant location, humanity’s first foray into the limitless bounds beyond our solar system’s edge. In hot pursuit, however, is a far more advanced vehicle, sporting improved instruments, updated optics, and even a means to sample the interstellar medium itself. New Horizons was launched from Earth in 2006 on a mission to visit Pluto, arriving in 2015 and revealing incredible details during its all-too-brief flyby. The spacecraft has continued its cruise toward interstellar frontiers ever since. It has now begun its second extended mission, and is soon set to wake up from a deep hibernation, opening a wealth of new science opportunities in the outer solar system. “It takes a long time to get to where our spacecraft is,” says Alice Bowman, mission operations manager for New Horizons at the Johns Hopkins University Applied Physics Laboratory (JHUAPL) in Maryland. “When you have a spacecraft that is out in that part of the solar system, it is a huge asset to the scientific community. There are so many unique things that a spacecraft that is out that far can do. We definitely want to take advantage of that.”https://www.scientificamerican.com/article/nasas-pluto-spacecraft-begins-new-mission-at-the-solar-systems-edge/?fbclid=IwAR3huhKYUaSJn34Gc4ueMkbuuJY3DyBb4BWYSNpZaSui1mQ-hAbL_bhfAXE

1/20/2023 4:00 PMHundreds of millions of light-years away in a distant galaxy, a star orbiting a supermassive black hole is being violently ripped apart under the black hole’s immense gravitational pull. As the star is shredded, its remnants are transformed into a stream of debris that rains back down onto the black hole to form a very hot, very bright disk of material swirling around the black hole, called an accretion disc. This phenomenon—where a star is destroyed by a supermassive black hole and fuels a luminous accretion flare—is known as a tidal disruption event (TDE), and it is predicted that TDEs occur roughly once every 10,000 to 100,000 years in a given galaxy.https://phys.org/news/2023-01-team-physicists-star-orbit-supermassive.html?fbclid=IwAR2i_9FWsLKvC0pNjPnXvxhr7cFnrSvsrjuPf0WKXecAapsh2RT4Uxfw-Pw

1/21/2023 8:00 AMAs all good whisky enthusiasts and connoisseurs will tell you, a drop of water in your dram enhances the smell and flavor of the smoky, golden liquid. Turning to the slightly unconventional use of computer simulations, scientists have now been able to explain exactly why a dribble of water helps the tipple. “The taste of whisky is primarily linked to so-called amphipathic molecules, which are made up of hydrophobic and hydrophilic parts,” explained Björn Karlsson, co-author of the study published in Scientific Reports. This basically means that one side of the ‘taste’ molecules in whisky is attracted to water, while the other is repelled by water. And it turns out that this two-ended structure in one such molecule known as guaiacol has a major bearing on the intoxicant’s flavor.https://www.iflscience.com/scientists-have-figured-out-exactly-why-whisky-tastes-better-with-water-43322?fbclid=IwAR0NFbVHy8kqjoxZCJlAnTR1CPhPIt10Z0B947GUL7xR7TmIQtc6torFYkY

Our sun is at times dotted with sunspots, cool dark regions on the stellar surface generated by strong magnetic fields, which suppress churning motions and impede the free escape of light. On other stars, these phenomena are called starspots, said Lyra Cao, lead author of the study and a graduate student in astronomy at The Ohio State University.https://phys.org/news/2023-01-astronomers-technique-starspots.html?fbclid=IwAR2g45FxfK_EkaZ4rPRPQQHM_SzSv0sCRwrY_TJmLvBC4QDsx0zfA1OupSA

Scientists often turn to complex machine-learning algorithms, but these can’t yet replace human intuition and our brains’ superb pattern-recognition skills. However, a combination of the two could be a perfect team.

An alternative approach is to comprehensively improve ecological processes and habitats, thereby supporting entire species communities. This so-called ecosystem-based management is however rarely implemented because it is costly.

NASA, the ESA, India, and Japan all have upcoming missions, and the coming decades are slated for ambitious attempts to retrieve samples and even put human boots in the soil. But this isn’t the first time the red planet has drawn our attention. While the 20th century’s space race is historically associated with the moon, the United States and Soviet Union also launched a slate of Mars missions. The USSR was especially attracted to Mars, seeing it as an opportunity to score their own historic moments after the American success of Apollo 11. And on December 2, 1971, Mars 3 achieved orbit, then sent down a lander that became the first spacecraft to safely touch Mars.https://astronomy.com/news/2021/12/50-years-ago-a-forgotten-mission-landed-on-mars?fbclid=IwAR3wB-iJBMrml8u4rvRy9GZ-PA0HU_TogCDk38r5nww2JHqB5hqMiUF_gfQ

3/8/2023 12:00 PMSt. Augustine said of time, “If no one asks me, I know what it is. If I wish to explain to him who asks, I don’t know.” Time is an elusive concept: We all experience it, and yet, the challenge of defining it has tested philosophers and scientists for millennia. It wasn’t until Albert Einstein that we developed a more sophisticated mathematical understanding of time and space that allowed physicists to probe deeper into the connections between them. In their endeavors, physicists also discovered that seeking the origin of time forces us to confront the origins of the universe itself.https://astronomy.com/magazine/news/2022/05/the-struggle-to-find-the-origins-of-time?fbclid=IwAR0YJjlmQQ-F5A8C1uD2J-WDc40aNOmIHaX46s3ySnNiICa6OARMRP4zhi8

4/18/2023 6:00 PMSomething in outer space is breaking the law — the laws of physics, that is. Astronomers call these lawbreakers ultraluminous X-ray sources (ULXs), and they exude about 10 million times more energy than the sun. This amount of energy breaks a physical law known as the Eddington limit, which determines how bright something of a given size can be. If something breaks the Eddington limit, scientists expect it to blow itself up into pieces. However, ULXs “regularly exceed this limit by 100 to 500 times, leaving scientists puzzled,” according to a NASA statement(opens in new tab).https://www.space.com/object-10-million-times-brighter-than-sun-defies-physics?fbclid=IwAR3_WKEb4bKgUm93TqkPtPmqhP-zo3D0bGXkW4ERdJIOtips4WudoTCd6cM

5/7/2023 6:00 PMBy studying countless stars at various stages of their evolution, astronomers have been able to piece together an understanding of the life cycle of stars and how they interact with their surrounding planetary systems as they age. This research confirms that when a sun-like star nears the end of its life, it expands anywhere from 100 to 1,000 times its original size, eventually engulfing the system’s inner planets. Such events are estimated to occur only a few times each year across the entire Milky Way. Though past observations have confirmed the aftermath of planetary engulfments, astronomers have never caught one in the act, until now.https://phys.org/news/2023-05-astronomers-witness-star-devouring-planet.html?fbclid=IwAR0TCajE-LV6SJEGJNfJkdPS_3the4aZDq75rKRIxb5I2GkqpPTdyANbsOQ

5/10/2023 4:00 PMWhen Edwin Hubble observed distant galaxies in the 1920s, he made the groundbreaking discovery that the universe is expanding. It was not until 1998, however, that scientists observing Type Ia supernovae further discovered that the universe is not just expanding but has begun a phase of accelerating expansion. “To explain this acceleration, we need a source,” says Joseph Mohr, astrophysicist at LMU. “And we refer to this source as ‘dark energy,’ which provides a sort of ‘anti-gravity’ to speed up cosmic expansion.”https://phys.org/news/2023-05-x-ray-telescope-dark-energy-uniformly.html?fbclid=IwAR3Rlt4zt0rBHujnzvsvoboVkSYaWbyfeL5Xc3F9Zd2PiLFeB2qK4ebPD14

5/11/2023 10:00 AMMars is a planet of vast contrasts — huge volcanoes, deep canyons, and craters that may or may not host running water. It will be an amazing location for future tourists to explore, once we put the first Red Planet colonies into motion. The landing sites for these future missions will likely need to be flat plains for safety and practical reasons, but perhaps they could land within a few days’ drive of some more interesting geology.
