The farthest things from Earth are extremely distant galaxies, like MoM-z14, a candidate identified with a redshift suggesting it existed less than 280 million years after the Big Bang, making it incredibly far, potentially billions of light-years away. For man-made objects, Voyager 1 holds the record, having left the solar system and traveling into interstellar space, making it the most distant human creation, currently billions of miles from Earth and still transmitting data, as noted by NASA Science and Space.com.
Voyager 1 is, at present, the farthest man-made object from the Earth. It's farther away from our planet than any other human creation. It is whizzing past the outer reaches of our Solar System, making it the farthest human footprint out there in the vacuum of space.
Both Voyagers will eventually collide with something, most likely the remnants of a star, but this will take an extraordinarily long time. The Voyagers' highest chances of collision were in the solar system, around the planets and in the asteroid and Kuiper belts, which they have already safely traversed.
What lies beyond the universe? We are not sure but can theorize what lies beyond the universe that we know. Outside the bounds of our universe may lie a "super" universe. Space outside space that extends infinitely into what our little bubble of a universe may expand into forever.
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.
Because of their relatively low speed (around 60,000 km/h)—relative to the galactic core of our galaxy, they will probably remain in orbit around the galactic core, and thus will never leave the Milky Way.
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.
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.
In 1 sextillion years (10²¹ years), the universe will be a vastly different, dark place: the era of star formation will have ended, all stars will have burned out into white dwarfs, neutron stars, or black holes, planets will be cold and lifeless, and even protons might begin to decay, leading towards the "Big Freeze" or heat death, with only black holes slowly evaporating via Hawking radiation over unimaginable timescales. All familiar structures, including galaxies, will have long dissolved as the universe expands, leaving behind a cold, dark, and nearly empty expanse.
About 95% of the universe is "invisible" because it's composed of dark matter (around 27%) and dark energy (around 68%), which don't emit, absorb, or reflect light, unlike the normal matter (stars, planets, us) that makes up the visible 5%. Dark matter's presence is inferred through its gravitational pull on visible galaxies, while dark energy is a mysterious force causing the universe's accelerated expansion.
Although it's unlikely, asteroid could hit Earth in 2030
The massive space rock--the first object to score above zero on the Torino hazard scale, which ranks the danger of an extraterrestrial impact--has about 1 chance in 500 of colliding with Earth in 2030, astronomers estimate.
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.
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.
Even a small move closer to the sun could have a huge impact. That's because warming would cause glaciers to melt, raising sea levels and flooding most of the planet. Without land to absorb some of the sun's heat, temperatures on Earth would continue to rise.
After Voyager 1 took its last image (the "Solar System Family Portrait" in 1990), the cameras were turned off to save power and memory for the instruments expected to detect the new charged particle environment of interstellar space. Mission managers removed the software from both spacecraft that controls the camera.
Although sky surveys such as Wide-field Infrared Survey Explorer (WISE) and Pan-STARRS did not detect Planet Nine, they have not ruled out the existence of a Neptune-diameter object in the outer Solar System. The ability of these past sky surveys to detect Planet Nine was dependent on its location and characteristics.
Humans Could Live For 1,000 Years by 2050—Ushering in the Dawn of 'Practical Immortality,' Futurists Say. Some experts warn that this radical change may remain out of reach for many, due to societal and economic challenges. Technology futurists foresee advances that will enable humans to live up to 1,000 years.
Based on known risks, the really cataclysmic ones, those that might exterminate us as a species, are fairly rare. Based on what we know today, it would be very unlikely that we wouldn't be around in the year 3000. There certainly would be bad times, but some of us would get through it.
Finally, the planet will likely be absorbed by the Sun in about 7.5 billion years, after the star has entered the red giant phase and expanded beyond the planet's current orbit.
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.
We are extremely confident black holes exist due to overwhelming evidence like stars orbiting invisible, super-massive objects (Sagittarius A*), gravitational waves from merging black holes detected by LIGO, and direct imaging of their shadows by the Event Horizon Telescope (EHT). While "100% sure" is rare in science, the consistency between Einstein's relativity, observed phenomena, and these new direct proofs leaves virtually no doubt within the scientific community.
The pain experience reported by both astronauts aligns with previous findings in astronauts exposed to microgravity. The term “space adaptation pain” is used to describe the acute onset of low back pain occurring within the first 24–48 hours of exposure to microgravity, lasting for 9–15 days.
Astronauts actually age slower in space because time dilation is governed by two variables: the gravitational force acting on the object and the relative velocity of the object. The faster an object moves, the slower time moves for it, according to the theory of relativity.
Water is the lifeblood of human survival and civilization and is critical for our sustained exploration beyond Earth. Fortunately, Mars has plenty of water to sustain our aspirations in the form of subsurface ice. Unfortunately, it is not clean water – it is contaminated by toxic perchlorates.
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.
