New Horizons mission continues to surprise scientists.

The Jupiter Icy Moons Explorer (JUICE) mission run by the European Space Agency (ESA) has taken the sharpest images ever produced of the Earth’s radiation belt. JUICE has a long mission ahead of it. Launched in April 2023, the spacecraft has to make several gravitational assists before it reaches its target of Jupiter and three of its largest moons…
Working towards the achievement of interstellar flight through knowledge to the stars — Starships in our lifetime.
University of Florida horticulture science professor Rob Ferl is going where some men have gone before, including William Shatner and Jeff Bezos, but he’s bringing along some experimental plant life for NASA.
Ferl, a researcher within UF’s Institute of Food and Agricultural Sciences, is also the director of UF’s new Astraeus Space Institute. He is joining five other people on the launch of Blue Origin’s suborbital New Shepard rocket today for what will be its eighth human spaceflight. Dubbed NS-26, the capsule is set for liftoff as early as 9:00 a.m. EDT from Blue Origin’s West Texas launch facility.
Along for the ride will be a species of plant called Arabidopsis thaliana. Ferl will be looking at how its genes adapt on the way to space.
Gravity is no longer a mystery to physicists—at least when it comes to large distances. Thanks to science, we can calculate the orbits of planets, predict tides, and send rockets into space with precision. However, the theoretical description of gravity reaches its limits at the level of the smallest particles, the so-called quantum level.
And luckily for us, quantum physicists think they know how to reach that higher dimension.

“With the printing of the first metal 3D shape in space, ESA Exploration teams have achieved a significant milestone in establishing in-orbit manufacturing capabilities. This accomplishment, made possible by an international and multidisciplinary team, paves the way for long-distance and long-duration missions where creating spare parts, construction components, and tools on demand will be essential,” said Daniel Neuenschwander, director of Human and Robotic Exploration at ESA, in a statement.
This groundbreaking technology continues to expand its applications on Earth, revolutionizing fields such as medicine, fashion, art, construction, food production and manufacturing. In space, as long-duration missions to the moon and potentially Mars take shape, astronauts will need a means of independently repairing or creating tools or parts for machinery or structures that would be difficult to carry onboard a spacecraft, which have limited capacity.
Australian physicists resolve time travel paradox, showing it could be possible according to einstein’s theory.
Australian physicists have demonstrated that time travel could be theoretically possible by resolving the classic grandfather paradox. By aligning Einstein’s theory of general relativity with classical dynamics, researchers at the University of Queensland showed that time travel scenarios, such as altering past events, can coexist without resulting in logical inconsistencies. They used a model involving the coronavirus pandemic to illustrate how events would adjust themselves to avoid paradoxes. This research suggests that time travel, while complex, does not inherently create contradictions and could be feasible according to current mathematical models.
After reading the article, a Reddit user named Harry gained more than 524 upvotes with this comment: Isn’t the problem with time travel that it is also space travel? The earth isn’t in the same spot now as it was when you first started reading my comment, the earth travels very fast in space so wouldn’t you also have to find out where in space the earth was in 1950 (chose random date) in order to physically travel there? And how could we know where in physical space the earth was in 1950?
