Could Astronauts Hibernate on Long Space Voyages?

A renewed era of space exploration is upon us, and many exciting missions will be headed to space in the coming years. These include crewed missions to the Moon and the creation of permanent bases there. Beyond the Earth-Moon system, there are multiple proposals for crewed missions to Mars and beyond. This presents significant challenges since a one-way transit to ...

PLD Space. Almost 5 years of the first launch delays.

The most famous space companies reaching a new level of technology and developing reusable vehicles are located in the United States. Nevertheless, Europe is trying to keep up and present its competitors to such well-known giants as SpaceX. PLD Space is one of them as it intends to become the first space company in Europe that create reusable space launch ...

Finally, a Practical use for Space-Based Power Beaming. Sending Power to Satellites in Shade

Power beaming is one of those technologies that can completely change the world.  Almost unlimited power wherever it is needed, whenever it’s needed, is literally a technology straight out of science fiction.  Researchers have been working on the technology for decades at this point, but there has been little commercial headway so far, so what is holding this revolutionary technology ...

A Detailed Scan of the Milky Way Finds Possible “Fossil” Spiral Arms

As we learn more about the cosmos, it’s interesting how some of the greatest discoveries continue to happen close to home. This is expected to continue well into the future, where observations of Cosmic Dawn and distant galaxies will take place alongside surveys of the outer Solar System and our galaxy. In this latter respect, the ESA’s Gaia observatory will ...

Primordial Black Holes Could Explain Dark Matter and the Growth of Supermassive Black Holes at the Same Time

It’s that time again. Time to look at a possible model to explain dark matter. In this case, a perennial favorite known as primordial black holes. Black holes have long been proposed as the source of dark matter. In many ways, they are the perfect candidate because they only interact with light and matter gravitationally. But stellar-mass black holes have ...

A Sun-Like Star Just Blasted out a Flare That Would be Devastating if it Happened Here

In the search for “potentially-habitable” extrasolar planets, one of the main things scientists look at is stellar activity. Whereas stars like our own, a G-type (G2V) yellow dwarf, are considered stable over time, other classes are variable and prone to flare-ups – particularly M-type red dwarf stars. Even if a star has multiple planets orbiting within its habitable zone (HZ), ...
