Challenging Conventional Wisdom: New Discovery Transforms Our Understanding of Crystals

For many, the word “crystals” conjures images of shimmering suncatchers that create a prism of rainbow colors or semi-transparent stones thought to possess healing abilities. But in the realm of science and engineering, crystals take on a more technical definition. They’re perceived as materials whose components – be it atoms, molecules, or nanoparticles –are arranged regularly in space. In other words, crystals are defined by the regular arrangement of their constituents. Familiar examples include diamonds, table salt, and sugar cubes.

Astronomers identify the coldest star yet that emits radio waves

Astronomers at the University of Sydney have shown that a small, faint star is the coldest on record to produce emission at radio wavelength.

The ‘ultracool brown dwarf’ examined in the study is a ball of gas simmering at about 425 degrees centigrade—cooler than a typical campfire—without burning .

By contrast, the surface temperature of the sun, a nuclear inferno, is about 5,600 degrees.

India moon mission rocket blasts into space — BBC News

India has launched its third Moon mission and is hoping to become to the first to land near its south pole – which has rarely been explored.

If successful, the Chandrayaan-3’s orbiter, lander and a rover are due to touch down on the Moon’s surface on 23 or 24 August.

The rocket set off from Satish Dhawan Space Centre space centre just after 09:05 GMT (10:05 BST; 14:35 local time).

The launch by the Indian Space Research Organisation (Isro) is the country’s first major mission since Prime Minister Narendra Modi’s government announced policies to spur investment in the space industry.

Scientist protects crafts from space debris in the Earth-Moon region

A Purdue University engineer is exploring how to spot and track all human-made objects and predict the impact of their potential damage in the Cislunar region.

To protect new craft from being hit by such space waste, Purdue University engineer Carolin Frueh is exploring how to spot and keep track of all human-made objects and predict the impact of their potential damage in this Earth-Moon neighborhood, called the Cislunar region.


Space is crowded. Particularly the region between Earth and the Moon. That part is full of space debris.

This is according to a press release by the institution published on Wednesday.

New research puts age of universe at 26.7 billion years, nearly twice as old as previously believed

Our universe could be twice as old as current estimates, according to a new study that challenges the dominant cosmological model and sheds new light on the so-called “impossible early galaxy problem.”

The work is published in the journal Monthly Notices of the Royal Astronomical Society.

“Our newly-devised model stretches the galaxy formation time by a several billion years, making the 26.7 billion years old, and not 13.7 as previously estimated,” says author Rajendra Gupta, adjunct professor of physics in the Faculty of Science at the University of Ottawa.
