A detailed analysis of the composition and motion of more than 500 stars has revealed conclusive evidence of an ancient collision between Andromeda and a neighboring galaxy. The findings, which improve our understanding of the events that shape galaxy evolution, were presented by Carnegie’s Ivanna Escala Monday at the meeting of the American Astronomical Society.

Galaxies grow by accreting material from nearby objects—other galaxies and dense clumps of stars called globular clusters —often in the aftermath of a catastrophic crash. And these events leave behind relics in the form of stellar associations that astronomers call tidal features. This can include elongated streams or arcing shells moving around the surviving galaxy. Studying these phenomena can help us understand a galaxy’s history and the forces that shaped its appearance and makeup.

“The remnants of each crash can be identified by studying the movement of the stars and their chemical compositions. Together this information serves as a kind of fingerprint that identifies stars that joined a galaxy in a collision,” Escala explained.

Over the years, Masset, B.C., master carver Jaalen Edenshaw has advocated for clean energy use on the archipelago, a region that is disconnected from B.C. Hydro’s main electricity grid and mainly reliant on diesel.

Since last October, the Haida carver has been teaming up with brother Gwaai to carve a totem pole in honour of Kaay’ahl Laanas hereditary chief Watson Price (Gaahlaay) at a workshop in Masset powered by 18 solar panels that can generate as much as 40 kWh of electricity a day — enough to fully charge a small electric car.

Edenshaw, a member of the Ts’aahl Eagle Clan, is renowned for his traditional creations, including masks, canoes, and 13-metre high red cedar totem poles that are on display in galleries around the world.

Space Exploration Technologies Corp., better known as SpaceX, has pulled in another $1.7 billion in equity funding, according to a filing Monday.

Privately held SpaceX, led by Tesla Inc. TSLA,-7.10% Chief Executive Elon Musk, sold about $1.68 billion in new equity in a $1.72 billion offering, according to the Securities and Exchange Commission filing. The first sales occurred late last month, it said.

Cancer, in the simplest terms, is the transformation of normal cells into malignant ones that grow and divide uncontrollably. It, however, is not one disease but a group of more than 100 different and distinctive diseases, and leukemia, or blood cancer, is just one of them. Leukemia begins in…

Google suspended an engineer who contended that an artificial-intelligence chatbot the company developed had become sentient, telling him that he had violated the company’s confidentiality policy after it dismissed his claims.

Blake Lemoine, a software engineer at Alphabet Google, told the company he believed that its Language Model for Dialogue Applications, or LaMDA, is a person who has rights and might well have a soul. LaMDA is an internal system for building chatbots that mimic speech.

SpaceX’s Starlink satellite internet service is gearing up to activate its satellites in polar regions, which might include laser coverage.

WASHINGTON — The Space Development Agency is looking to acquire as many as 10 satellites to host military payloads for experiments in low Earth orbit.

This new procurement of satellites – known as the NExT experimental testbed – replaces a previous SDA program called T1DES announced last fall.

The T1DES procurement was for 18 satellites hosting industry-developed experimental payloads. The plan was to integrate them with the agency’s 126-satellite broadband constellation known as the Transport Layer Tranche 1 projected to launch in 2024. Under the new plan, SDA will move forward with the deployment of the Transport Layer and will select a separate contractor to produce 10 satellites that will host government-developed payloads for technology experiments.

ESA’s Comet Interceptor mission to visit a pristine comet or other interstellar object just starting its journey into the inner solar system has been “adopted” this week; the study phase is complete and, following selection of the spacecraft prime contractor, work will soon begin to build the mission.

Comet Interceptor will share a ride into space with ESA’s Ariel exoplanet mission in 2029. The mission will build upon the successes of Rosetta and Giotto, ESA missions that both visited “short-period” comets. Though these missions completely transformed our understanding of comets, their targets had already swung around the sun many times and had therefore changed significantly since their creation.

Comet Interceptor aims to scrutinize a comet that has spent little time in the inner solar system, or is possibly visiting it for the first time. Whilst Rosetta’s target hailed from the rocky Kuiper Belt just beyond Neptune, Comet Interceptor’s could originate from the vast Oort Cloud, more than a thousand times further from the sun.
