There's no "under" the Earth in space because space has no up or down; it's a 3D environment where "below" from our perspective is simply outward in the opposite direction, revealing other parts of our galaxy, stars, and deep space, but our solar system is mostly flat, so you'd encounter empty space until you reach distant galaxies. "Underneath" Earth's surface are its hot core, mantle, and crust, containing unique structures like massive blobs of ancient material, while the entire planet is surrounded by the vacuum of space.
There isn't really a below or above in space. Yes galaxies will have disc shapes because of gravity effects, but these galaxies will be spread (somewhat) randomly troughout the universe. The universe itself is shaped somewhat like a ball.
Return to the Moon
Artemis II, scheduled for launch between February and April sees the return of the first people to the Moon since Apollo 17 in 1972. Three American and one Canadian astronaut will orbit the Moon on a 10 day journey that lays the foundation for lunar landings in the coming years.
Deep space could be simply defined, as a part of the universe, which is lying beyond the Earth-Moon system. However, when speaking about deep space objects we generally mean stars, star clusters and nebulae, which are outside the Solar System.
Deep Amazon and other rainforests, large parts of mountain ranges (only the peaks are climbed. Nobody has explored the entire Himalayan range, for instance), many areas in the desert, etc.
Once every 176 years, the giant planets on the outer reaches of the solar system all gather on one side of the sun, and such a configuration was due to occur in the late 1970s.
But eventually, the lack of oxygen will take its toll. One by one, your major organs will shut down. After only a handful of minutes you will suffer complete organ failure, otherwise known in the medical community as death.
Space, or outer space, is a vast, near-perfect vacuum largely devoid of matter. This vacuum contains very few particles compared with Earth's atmosphere. However, it's not entirely empty. Space is dotted with scattered matter called the interstellar medium, which includes hydrogen and helium atoms.
Who are the two astronauts who were stuck in space? The two astronauts who were stranded on board the International Space Station (ISS) are 59-year-old Sunita “Suni” Williams and Barry “Butch” Wilmore, 62, both veteran NASA-trained space travellers.
For Elon Musk, the number 42, famously from The Hitchhiker's Guide to the Galaxy, signifies humanity's quest for answers, reminding us that asking the right questions about life, the universe, and our purpose is crucial, especially in space exploration, serving as an inspiration for progress and seeking deeper meaning beyond just technology. He's incorporated it into SpaceX's Starship, symbolizing this ongoing search for meaning and the universe's profound mysteries.
2026 is significant due to major global events like the FIFA World Cup and Winter Olympics, crucial shifts in technology and labor (AI, automation, mass retirements), start of a new numerological cycle (Universal Year 1), increased focus on climate and humanitarian efforts (International Year of Rangelands), and escalating geopolitical tensions that may reshape global power structures, making it a pivotal year for new beginnings and potential instability.
Astronomers have found an unusually large planet orbiting a small star, located about 280 light-years from Earth. The unexpected size of the newly discovered world, called TOI 5205b, has led researchers to call it the “forbidden planet.”
Earth will last for billions of years, but life as we know it will likely end in about 1 billion years as the Sun gets hotter and boils the oceans, making the planet too hot and oxygen-poor; the planet itself will remain until the Sun expands into a red giant in roughly 5 billion years, eventually engulfing it. While minor geological events or asteroid impacts pose shorter-term risks, the Sun's increasing luminosity is the ultimate deadline for Earth's habitability and physical existence.
On April 13, 2029, the large asteroid Apophis (99942) will have a very close, but safe flyby of Earth, passing within 32,000 kilometers (20,000 miles) of our planet—closer than some satellites—and will be visible to the naked eye in the night sky from parts of the Eastern Hemisphere (Europe, Africa, Asia) as a bright, fast-moving point of light. This rare event offers scientists a unique opportunity to study an asteroid of its size (about 375 meters wide) up close, with missions like NASA's OSIRIS-APEX and ESA's Ramses planned to observe it.
Fresh milk is yet another commodity prohibited in space due to its perishable nature. Milk would spoil within a few hours in the zero-gravity environment, which would be harmful for health if not refrigerated. Astronauts use powdered or ultra-pasteurized milk instead, which has a much longer shelf life.
Krikalev is sometimes referred to as the "last Soviet citizen," having been aboard Mir during the dissolution of the Soviet Union. With the country that launched him no longer existing, his return was delayed, and he remained in space for 311 days—twice as long as planned.
Black holes
A black hole is a region of space so dense, nothing can escape its its gravitational pull: not even light or any other form of electromagnetic radiation. Cross its 'event horizon' and you'll disappear forever. And astronomers now think there's a supermassive black hole at the centre of most galaxies.
Because the Milky Way and its closest neighbors are separated by millions of light-years, any such venture would also require millions of years based on our current understanding of physics. Thus, intergalactic travel is impossible within the human lifetime.
Mars is one of the most explored bodies in our solar system, and it's the only planet where we've sent rovers to roam the alien landscape.
Where are Voyager 1 and Voyager 2 Now? Both Voyager 1 and Voyager 2 have reached interstellar space and each continue their unique journey deeper into the cosmos.
North Sentinel Island, India
One of the last untouched civilisations on Earth lives on North Sentinel Island. The Sentinelese tribe has remained isolated for over 60,000 years, rejecting any contact with the outside world.
There are still some places on Earth that have not been explored much by people. The ocean is one of these places. It covers more than 70% of Earth's surface, and it contains many types of ecosystems.
Most of the ocean remains unexplored (around 80-95%) due to its immense size, extreme darkness, near-freezing temperatures, crushing pressure (over 1,000 times surface pressure in the deep), and the high cost and technological challenges of developing specialized equipment to withstand these harsh, hostile conditions. Sunlight can't penetrate far, visibility is near zero, and deep-sea life is adapted to pressure that would crush most vessels, making direct human study difficult and expensive.
