What part of a space rock survives to the ground?
Tuesday, 09 August 2022 01:30
When a small asteroid enters Earth's atmosphere from space, its surface is brutally heated, causing melting and fragmenting. Therefore, it was somewhat of a mystery why the rocks near the surface survive to the ground as meteorites. That mystery is solved in a new study of the fiery entry of asteroid 2008 TC3, published online in Meteoritics and Planetary Science.

"We've got thumbnails!!" shouted, emotionally, over excited celebrations, is my most intense memory from 10 years ago. I had sat, with a lot of colleagues from my home university, The Open University here in the UK, in a seminar room, NASA TV on the big screen, anxiously watching the proceedings since 6.30 am on the 6th of August. The UK is 8 time zones ahead of Pasadena in California, where it Lowell Observatory points telescopes at Saturn during closest annual approach

Saturn will soon be at its biggest and brightest of the year, and Lowell Observatory is celebrating with nightly public telescope viewing. For the next several weeks, visitors will be able to gaze at this gas giant and see its dazzling system of rings, as well as some of its larger moons.
This Saturn viewing season centers around the planet's August 14 opposition. The term opposition indic Stars shed light on why stellar populations are so similar in Milky Way

Scientists have uncovered what sets the masses of stars, a mystery that has captivated astrophysicists for decades. Their answer? Stars, themselves.
Using highly detailed simulations, a collaborative team led by researchers from the University of Texas at Austin has made a breakthrough discovery that star formation is a self-regulatory process, knowledge that may allow researchers to under Stars determine their own masses

Last year, a team of astrophysicists including key members from Northwestern University launched STARFORGE, a project that produces the most realistic, highest-resolution 3D simulations of star formation to date. Now, the scientists have used the highly detailed simulations to uncover what determines the masses of stars, a mystery that has captivated astrophysicists for decades.

Commercial satellite race raises calls for more regulations
Monday, 08 August 2022 17:10
Rapidly evolving technology and space debris reported in several places around the world—including pieces of a Chinese Long March 5B Rocket in the Indian Ocean—signal the need for a new era for regulation of space, Flinders University experts say.
Their timely new report is calling on governments to pay more attention to the use of low-Earth orbit as space laws and technologies race ahead at high speed.
Ahead of a meeting of intergovernmental experts at next year's World Radio Conference, the space experts from the Flinders University's Jeff Bleich Centre are raising concerns on several fronts, commencing with the takeoff of commercial interest in satellite "mega-constellations" in Low-Earth Orbit (LEO).
"While there are laws that cover space activities, they are already under stress because of the speed at which the commercial space industry is evolving," says research associate in space law Joel Lisk, from the Jeff Bleich Centre at Flinders University's College of Business, Government and Law.
"There is a need to work towards ensuring that we have broad and flexible regulatory settings that are geared to rapid change and future developments.
