2017 was a year of excitement among the asteroid-watching community, as ‘Oumuamua, the first recorded visitor from an another solar system, took a spin around our sun before launching itself off into the inky blackness of space.
According to a team at the University of Johannesburg, though, ‘Oumuamua is far from the first visitor from another solar system that we have available to study. One such alien rock is right here on Earth, making it far easier to study.
The 11,500-year-old remains of an infant girl from Alaska have shed new light on the peopling of the Americas.
Genetic analysis of the child, allied to other data, indicates she belonged to a previously unknown, ancient group.
Scientists say what they have learnt from her DNA strongly supports the idea that a single wave of migrants moved into the continent from Siberia just over 20,000 years ago.
Jupiter’s atmosphere is quite simply a work of art. With an atmosphere that best resembles the sun, Jupiter is predominantly made up of hydrogen and helium, with trace amounts of ammonia, sulfur, methane and water vapor. Strong east-west winds in the planet’s upper atmosphere travel at 400 mph, with dark belts and light zones reflecting different compositions of chemicals.
NASA and Google on Thursday announced what they called a “major discovery”: another solar system with eight planets.
Astronomers already knew about the star system, called Kepler-90, and seven of its planets. But by using new artificial-intelligence software developed by Google, researchers identified an eighth planet, Kepler-90i, lurking in old data.
The 2009 film “Avatar” created a lush imaginary world, illuminated by magical, glowing plants. Now researchers are starting to bring this spellbinding vision to life to help reduce our dependence on artificial lighting. They report in ACS’ journal Nano Letters a way to infuse plants with the luminescence of fireflies.
In January 2015, NASA released the largest image ever of the Andromeda galaxy, taken by the Hubble telescope. Totaling 1.5 billion pixels and requiring 4.3 gigabytes of disk space, this photo provides a detailed glimpse at the sheer scale of our nearest galactic neighbor.
Scientists have identified a new form of matter, the existence of which has been theorised for 50 years.
The substance is known as “excitonium”.
It is made up of excitons – unusual particles made up of an escaped electron and the hole it has left behind in a material.
Why should we go to space? To learn more about the universe and our place in it? To extract resources and conduct commerce? To demonstrate national primacy and technological prowess? To live and thrive in radically different kinds of human communities? Visions, Ventures, Escape Velocities takes on the challenge of imagining new stories at the intersection of public and private—narratives that use the economic and social history of exploration, as well as current technical and scientific research, to inform scenarios for the future of the “new space” era.
Blue whales, grays and humpbacks are traveling south along the California coast this month to their annual breeding grounds in warm Mexican waters. They feed in the same spots where cargo ships travel to some of the world’s busiest ports — and one strike could be deadly.
A weapon as legendary as the dagger of King Tutankhamun needs an epic backstory, and last year X-ray analysis showed that the iron in the ancient blade had come from meteorites. Now, a French study has found that the artifact was far from alone as all iron tools dating back to the Bronze Age have otherworldly origins.
A new type of 3-D printing ink has a special ingredient: live bacteria.
Materials made with this “living ink” could help clean up environmental pollution, harvest energy via photosynthesis or help make medical supplies, researchers report online December 1 in Science Advances.
After learning that a satellite that’s been silent for decades has suddenly started sending out new signals you may, of course, suspect that the device has been hijacked by aliens now trying to communicate with Earth. Perhaps they’re warning us that they are planning an invasion!
