NASA will not use Russian Progress spacecraft to vault the ISS from orbit — US companies will create a special vehicle

Posted by in category: space

NASA has updated its plan to decommission the International Space Station. The agency has decided not to use Russian Progress spacecraft.

Here’s What We Know

The federal agency will create a new spacecraft. Its development will be taken up by American companies. The decision is due to the deterioration of relations between the United States and the Russian Federation.

James Webb Space Telescope’s first spectrum of a TRAPPIST-1 planet

Posted by in category: space

In a solar system called TRAPPIST-1, 40 light years from the sun, seven Earth-sized planets revolve around a cold star.

Astronomers obtained new data from the James Webb Space Telescope (JWST) on TRAPPIST-1 b, the planet in the TRAPPIST-1 solar system closest to its star. These new observations offer insights into how its star can affect observations of exoplanets in the habitable zone of cool stars. In the habitable zone, liquid water can still exist on the orbiting planet’s surface.

The team, which included University of Michigan astronomer and NASA Sagan Fellow Ryan MacDonald, published its study in the journal The Astrophysical Journal Letters.

Rock that punched hole in New Jersey house confirmed to be 4.6 billion-year-old meteorite

Posted by in category: space

A metallic-looking rock that smashed through the roof of a residential home in New Jersey’s Hopewell Township earlier this week is indeed a meteorite — a rare one about 4.6 billion years old, scientists confirmed on Thursday (May 11).

“It was obvious right away from looking at it that it was a meteorite in a class called stony chondrite,” Nathan Magee, chair of the physics department at The College of New Jersey (TCNJ), whose office was contacted by the Hopewell Township police soon after the rock was found on Monday (May 8), told Space.com.

NASA’s Chandra rewinds story of great eruption of the 1840s

Posted by in category: space

Using snapshots taken over 20 years with NASA’s Chandra X-ray Observatory, astronomers have learned important new details about an eruption from Eta Carinae witnessed on Earth in the mid-19th century.

Chandra data spanning decades has been combined into a new movie that contains frames of Eta Carinae from 1999, 2003, 2009, 2014, and 2020. Astronomers used the Chandra observations, along with data from ESA’s (European Space Agency’s) XMM-Newton, to watch as the stellar from 180 years ago continues to expand into space at speeds up to 4.5 million miles per hour. The new insights gleaned from Eta Carinae show how different space observatories can work together to help us understand changes in the universe that unfold on human timescales.
