The two astronauts who made Boeing Starliner’s initial crewed flight test in June have now scheduled to return to Earth after their much-awaited return.

NASA astronauts Suni Williams and Butch Wilmore will be leaving the International Space Station (ISS) days after the landing of SpaceX’s next Crew-10 mission.

Crew-10, which has four astronauts on board, will launch next week and will take the place of the Crew-9 team that is currently on the ISS.

Lobster-eye satellite Einstein Probe captured the X-ray flash from a very elusive celestial pair. The discovery opens a new way to explore how massive stars interact and evolve, confirming the unique power of the mission to uncover fleeting X-ray sources in the sky.

The odd celestial couple consists of a big, hot star, more than 10 times larger than our Sun, and a small compact white dwarf, with a mass similar to our star. Only a handful of these systems have been found so far. And this the first time scientists could track the X-ray light coming from such a curious pair from its initial sudden flare-up to its fading away.

On 27 May 2024, the Wide-field X-ray Telescope (WXT) on Einstein Probe spotted X-rays coming from within our neighbour galaxy, the Small Magellanic Cloud (SMC). To uncover the origin of this new celestial beacon, labelled EP J0052, scientists pointed Einstein Probes’s Follow-up X-ray Telescope in that direction.

In the fall, the clocks “fall back” one hour at 2:00 a.m., instantly becoming 1:00 a.m.

This week, we will lose an hour on Sunday March 9. We will gain an hour on Sunday November 2.

Daylight-saving time was originally concocted as a way to save energy in the evenings, and was implemented during World War I in Germany.

I predict most of humanity will be living in space habitats by the end of century and the beginning of the 22nd century O’Neil colonies and generation ships will be built out of hollowed out asteroids and it will be like james blish cities in space and George zebrowskis macrolife the colonizing of the galaxy.

Why time passes is one of the biggest mysteries in physics, as the fundamental laws of nature don’t reflect a difference between moving forward and backward in time. In a new paper, researchers have shown that time might actually be able to run in two directions, meaning we might have a twin universe where time runs opposite our universe’s. Let’s take a look.

A story about traveling through time, literally.

When we fly, we often cross time zones, sometimes even when we drive. Imagine for a moment that this is a continuous process. Even as you walk, your zone moves just a little from one moment to another.

S assume that your personal noon is when the sun is highest. You can create the time for your own body with this calculator. ” + Give it a try. If you have an iPhone, open the included compass app to get the longitude and latitude required to set this personal clock. You can also use Google Earth with your browser to find your location and the lat and long in the bottom right.

Physicists have long attempted to find a single theory that unites quantum mechanics and general relativity.

This has been very tricky because quantum mechanics focuses on the unpredictable nature of particles at microscopic scales, whereas general relativity explains gravity as the curvature of spacetime caused by massive objects.

The two theories discuss forces existing on different scales. Bianconi employed an interesting approach to deal with this challenge. She proposes an entropic action where, instead of being a fixed background, spacetime works like a quantum operator — acting on quantum states and deciding how they change over time.

Centenarians, once considered rare, have become commonplace. Indeed, they are the fastest-growing demographic group of the world’s population, with numbers roughly doubling every ten years since the 1970s.

How long humans can live, and what determines a long and healthy life, have been of interest for as long as we know. Plato and Aristotle discussed and wrote about the ageing process over 2,300 years ago.

The pursuit of understanding the secrets behind exceptional longevity isn’t easy, however.
