Some of the most violent cosmic collisions occur silently in the vacuum of space, but with the right instrumental ears, we can still hear it happen. Here’s how.
Long considered the lifeline of the world’s most populous country, the 170-year-old system has seen rapid expansion and modernisation under Prime Minister Narendra Modi’s push to boost infrastructure and connectivity in the fast-growing economy.
This year, the government made a record 2.4-trillion-rupee ($30 billion) capital outlay for the railways, a 50% increase over the previous fiscal year, to upgrade tracks, ease congestion and add new trains.
A new, semi-high-speed train built in India and called the “Vande Bharat Express”, or “Salute to India Express”, is showcased as evidence of this modernisation, with Modi himself flagging off the first journeys of many of the trains around the country.
Updated on June 3: SpaceX has delayed the launch of its CRS-28 cargo mission to no earlier than Sunday, June 4, at 12:12 p.m. EDT (1612 GMT) due to bad weather and vehicle checks.
SpaceX will launch its 28th cargo mission to the International Space Station for NASA Sunday (June 4) after a one-day weather delay and you can watch the action live.
A recently discovered formation of galaxies spanning 3.3 billion light-years is one of the largest known structures in the universe, contradicting some of the most fundamental beliefs of astronomers about the cosmos. The Giant Arc is composed of galaxies, galaxy clusters, and a significant amount of gas and dust. It is located 9.2 billion light-years away and covers approximately one-fifteenth of the visible universe.
The discovery was “fortuitous,” according to Alexia Lopez, a doctoral candidate in cosmology at the University of Central Lancashire (UCLan) in the United Kingdom. Lopez was creating maps of the night sky using light from around 120,000 quasars, which are the bright centres of galaxies where supermassive black holes consume matter and generate energy.
By measuring magnesium’s imprints, Lopez could calculate the distance to the intervening gas and dust, as well as the composition of the substance. The quasars were used as “spotlights in a dark room,” illuminating the intervening matter, according to Lopez. A structure began to emerge in the middle of the cosmic maps, a massive arc that was an indication of the Giant Arc.
This episode begins a three-part series focusing more on the specifics of colonization including the human aspect of it. We lay the groundwork by looking at colonies just in our solar system before moving off in episodes two and three to look at life on colony ships and then on interstellar colonies.

This episode concludes a three-part series focusing more on the specifics of colonization including the human aspect of it. Today we journey to the Tau Ceti System after a 120 year voyage to join our colonists in the early days of the colony.

To travel to other planets, we will first have to build up are infrastructure closer to home, in orbit of Earth. The best place to get all the mass for those space stations and rocket fuel depots is from the Moon, and we’ll examine the milestones we’ll need to reach to start lunar resource harvesting and building up space settlements.

Scientists say they’ve successfully transmitted solar energy gathered in orbit down to the Earth’s surface.
A new study suggests that astrocytes, a type of brain cell, are important for connecting amyloid-β with the early stages of tau pathology, which could change how we define early Alzheimer’s disease.
