When testing Einstein's theory of general relativity, small modeling errors add up fast
Small modeling errors may accumulate faster than previously expected when physicists combine multiple gravitational wave events (such as colliding black holes) to test Albert Einstein's theory of general relativity, suggest researchers at the University of Birmingham in the United Kingdom.
The findings, published June 16 in the journal iScience, suggest that catalogs with as few as 10 to 3 How a supermassive black hole originates
Supermassive black holes, or SMBHs, are black holes with masses that are several million to billion times the mass of our sun. The Milky Way hosts an SMBH with mass a few million times the solar mass. Surprisingly, astrophysical observations show that SMBHs already existed when the universe was very young. For example, a billion solar mass black holes are found when the universe was just 6% of i SpaceML.org aims to accelerate AI application in space science and exploration
The SETI Institute and Frontier Development Lab are announcing the launch of SpaceML.org. SpaceML is a resource that makes AI-ready datasets available to researchers working in space science and exploration, enabling rapid experimentation and reproducibility.
The SpaceML Repo is a machine learning toolbox and community managed resource to enable researchers to more effectively engage in AI Researchers discover orbital patterns of trans-Neptunian objects
Trans-Neptunian Objects (TNOs), small objects that orbit the sun beyond Neptune, are fossils from the early days of the solar system which can tell us a lot about its formation and evolution.
A new study led by Mohamad Ali-Dib, a research scientist at the NYU Abu Dhabi Center for Astro, Particle, and Planetary Physics, reports the significant discovery that two groups of TNOs with differen Study of young chaotic star system reveals planet formation secrets
A team of scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) to study the young star Elias 2-27 have confirmed that gravitational instabilities play a key role in planet formation, and have for the first time directly measured the mass of protoplanetary disks using gas velocity data, potentially unlocking one of the mysteries of planet formation. The results of the research Orchids in orbit: Seeds tested in space
Almost 30 grams of Nanjing orchid seeds were carried into space for breeding tests, accompanying three Chinese astronauts in China's Shenzhou XII manned spaceship, which was launched on Thursday. The seeds will be in space for three months.
A red orchid variety, Hongcao, features red buds and seedlings, a popular variant from Nanjing county of Fujian province.

Earlier this year, media reported that Ankara was planning to build a spaceport in Somalia as part of a $1 billion investment in the nation's nascent space programme. Turkish authorities did not confirm this information, but President Recep Tayyip Erdogan did announce in February that Turkey would make a hard landing on the Moon by the year 2023.

It could be a milestone on the path to detecting life on other planets: Scientists under the leadership of the University of Bern and of the National Center of Competence in Research (NCCR) PlanetS detect a key molecular property of all living organisms from a helicopter flying several kilometers above ground. The measurement technology could also open up opportunities for remote sensing of the Earth.
Left hands and right hands are almost perfect mirror images of each other. But whatever way they are twisted and turned, they cannot be superimposed onto each other. This is why the left glove simply won't fit the right hand as well as it fits the left. In science, this property is referred to as chirality.
Just like hands are chiral, molecules can be chiral, too. In fact, most molecules in the cells of living organisms, such as DNA, are chiral. Unlike hands, however, that usually come in pairs of left and right, the molecules of life almost exclusively occur in either their "left-handed" or their "right-handed" version.
SpaceML.org: A new resource to accelerate AI application in space science and exploration
"SpaceML helped accelerate impact by bringing in a team of citizen scientists who deployed an interpretable Active Learning and AI-powered meteor classifier to automate insights, allowing the astronomers focused research for the SETI CAMS project," said Siddha Ganju, Self Driving and Medical Instruments AI Architect, Nvidia (founding member of SpaceML's CAMS and Worldview Search Initiatives). "During SpaceML we (1) standardized the processing pipeline to process the decade long meteor dataset collected by CAMS, and, established the state of the art meteor classifier with a unique augmentation strategy; (2) enabled active learning in the CAMS pipeline to automate insights; and, (3) updated the NASA CAMS Meteor Shower Portal which now includes celestial reference points and a scientific communication tool. And the best thing is that future citizen scientists can partake in the CAMS project by building on the publicly accessible trained models, scripts, and web tools.
Student experiments to blast off from NASA Wallops
After being developed via a virtual learning experience, more than 70 experiments built by university students across the United States are ready for flight on NASA suborbital flight vehicles.
The launch of a NASA Terrier-Improved Orion suborbital sounding rocket carrying some of the students' experiments will be conducted at 8 a.m. EDT, Thursday, June 24, from NASA's Wallops Flight Facility in Virginia. The rocket launch is expected to be seen from the eastern shore of Virginia and Maryland and southern Delaware.
"One of the great attributes of the NASA suborbital flight vehicles is the ability to support educational flight activities," said Giovanni Rosanova, chief of the NASA Sounding Rockets Program Office at Wallops. "Despite the challenges that dealing with COVID 19 presented, everyone came together to make this launch happen this year after having to postpone the project in 2020.
