Approximately one billion light-years from Earth, a massive elliptical galaxy has been found to be an avid recycler, although not of plastic bottles. At its core, the supermassive black hole is blasting cold molecular gas, which is then falling into the black hole, and feeding the cycle again and again.

This kind of phenomenon is called a "fountain", which is a galactic way to recycle star-forming material. Although it’s been a theory for a long time, it's never been observed in its entirety...until now.

Astronomers discovered this intriguing scene in a galaxy at the heart of a cluster called Abell 2597.

Grant Tremblay from the Harvard-Smithsonian Center for Astrophysics stated that this is possibly the first system where they have found clear evidence for both cold molecular gas inflow toward the black hole and outflow or uplift from the jets that the black hole launches.

Tremblay added that this supermassive black hole at the centre of this giant galaxy functions like a mechanical pump in a fountain.

In other news, a bizarre orange glow is actually known as airglow, courtesy of NASA.

As per NASA, the airglow is thin bands of light that span 50 to 400 miles into our atmosphere. It usually happens when molecules, mostly nitrogen and oxygen, are energized by ultraviolet radiation from sunlight.

From there, the atoms in the lower atmosphere collide with each other and lose energy in the crash. The result is colourful airglow, as NASA wrote on their website.

Furthermore, this particular airglow is orange. However, others have been rainbow-coloured, according to 

Moreover, recently Beijing held an event aimed at the future of housing. During this event, the company Open Architecture, in conjunction with Chinese electronics firm Xiaomi, revealed a tiny shelter for Mars. At this stage, it is very conceptual, and as of now, there's nothing to confirm the dwelling will be installed on the Red Planet. However, it's interesting to see the way the architects addressed the idea.

The Mars Case prototype drew inspiration from the book Walden by Henry David Thoreau. The concept is about simplicity and self-reliance (the book is a significant influence on the small living movement). The shelter measures 2.4 x 2.4 x 2 m (7.87 x 7.87 x 6.5 ft) and certainly looks the part, it is made up of a rectangular suitcase-like section and an inflatable bulbous front area.

The plan would be to transport the suitcase-like box to Mars somehow then, the bulbous inflatable part with integrated windows would expand outward automatically, resulting in a comfortable shelter.

Finally, NASA has started performing tests to determine how residents in Texas will react to noise from an experimental aircraft that will drastically cut flight times in half.

On Monday, the U.S. space agency began a research project, aiming to experiment for their next airliner, dubbed the X-59 or the 'Son of Concorde,' as aviation fans know it.

The goal of this project is to figure out if residents living near the Texas Gulf Coast will hear noise from the jets as they travel faster than the speed of sound. However, these jets are designed not to make the explosive sound of a sonic boom.

Do you think the Mars dwelling prototype is promising? Why? What else would you like to see incorporated in a habitat for colonizing Mars?
