JWST sees a stunning hourglass of light around a still-forming star

Posted by in category: space

About 450 light years away, a star is being born. The James Webb Space Telescope (JWST) has taken an image of a protostar – an object that is massive enough to become a star but hasn’t yet begun the process of nuclear fusion – revealing details that have never been seen before.

This protostar is in an area called the Taurus star-forming region, embedded within a dark cloud of dust and gas called L1527. It is only about 100,000 years old, putting it in the first stage of star formation, in which it is still slightly fluffy and lopsided. Over the next few million years, it will continue to compress under its own gravitational pull and then begin to fuse hydrogen into helium and become a fully fledged star.

Microbes may have survived for millions of years beneath the Martian surface

Posted by in categories: biological, particle physics, space

Ancient bacteria might be sleeping beneath the surface of Mars, where it has been shielded from the harsh radiation of space for millions of years, according to new research.

While no evidence of life has been found on the red planet, researchers simulated conditions on Mars in a lab to see how bacteria and fungi could survive. The scientists were surprised to discover that bacteria could likely survive for 280 million years if it was buried and protected from the ionizing radiation and solar particles that bombard the Martian surface.

The findings suggested that if life ever existed on Mars, the dormant evidence of it might still be located in the planet’s subsurface — a place that future missions could explore as they drill into Martian soil.

New Map of the Universe Displays Span of Entire Cosmos With Pinpoint Accuracy and Sweeping Beauty

Posted by in category: space

The map charts a broad expanse of the universe, from the Milky Way.

The Milky Way is the galaxy that contains our Solar System, and is named for its appearance from Earth. It is a barred spiral galaxy that contains an estimated 100–400 billion stars and has a diameter between 150,000 and 200,000 light-years.

ESA SOLARIS: Wireless Power Beamed Down From Space

Posted by in categories: business, government, solar power, space, sustainability

Solar power could be gathered far away in space and transmitted wirelessly down to Earth to wherever it is needed. The European Space Agency (ESA) plans to investigate key technologies needed to make Space-Based Solar Power a working reality through its SOLARIS initiative. Recently in Germany, one of these technologies, wireless power transmission, was demonstrated to an audience of decision-makers from business and government.

The demonstration took place at Airbus’ X-Works Innovation Factory in Munich. Microwave beaming was used to transmit green energy between two points representing ‘Space’ and ‘Earth’ over a distance of 36 meters.

Sun is Older Than The Earth But The Water You Drink is Older Than The Sun

Posted by in category: space

Remember that some of the molecules in your “fresh” sip of water are actually billions of years old—far older than the solar system itself.

It looks doubtful that water existed on Earth before the solar system in which it is located. However, a recent peer-reviewed study published in the journal Science supports this.

Astronomers arrived at this conclusion by demonstrating that water in our solar system had to have been produced inside the huge cloud of gas and dust that preceded and was required for the creation of the star known as the Sun. This implies that water existed before the Sun exploded into a star, water that eventually made its way to Earth via “wet rocks” such as asteroids or comets.

Latest Webb image shows what our Sun looked like as a baby protostar

Posted by in categories: nuclear energy, space

Webb’s NIRCam instrument recently captured this detailed image of the cloudy region around a very young protostar called L1527. Only about 100,000 years old, L1527 isn’t a star yet: it hasn’t fully pulled itself into a proper, stable sphere, and it hasn’t piled on enough mass to kickstart nuclear fusion and start pumping out its own energy. It’s more like “a small, hot, and puffy clump of gas, somewhere between 20 percent and 40 percent the mass of our Sun,” according to the European Space Agency.

But as the latest Webb photos reveal, the young protostar is making an ambitious start.
