Astronomers have used data from NASA’s Chandra X-ray Observatory to study the properties of dark matter, the mysterious, invisible substance that makes up a majority of matter in the universe. The study, which involves 13 galaxy clusters, explores the possibility that dark matter may be more “fuzzy” than “cold,” perhaps even adding to the complexity surrounding this cosmic conundrum.
Physicists have come up with what they claim is a mathematical model of a theoretical “time machine” – a box that can move backwards and forwards through time and space.
One of the most mysterious anomalies astronomers have detected in space is the CMB “Cold Spot,” a massive void in space where no cosmic microwave background radiation (CMB) is found. Cosmic background radiation – energy left over from the Big Bang – is believed to spread throughout the entire universe.
Professor Wright is an associate professor in astronomy and astrophysics at Pennsylvania State University.
In a new paper, titled ‘Prior Indigenous Technological Species’, Professor Wright suggests that ancient aliens could have lived on either Mars, Venus or even Earth.

Dust and rock particles that mimic regolith on the surfaces of the Moon and Mars have been turned into 3D printer inks, offering a glimpse into how humans might one day use local materials in situ to construct and maintain extraterrestrial outposts.
It will take more than six years to get there. But if long-anticipated signs of life are found on Europa, a newly-proposed joint American-European trek to the enigmatic moon of Jupiter will have been worth it.
China is talking with the European Space Agency about collaborating on a human settlement on the moon.
The secretary general for China’s space agency, Tian Yulong, disclosed the talks today in Chinese state media.
NASA is all about solving challenges, and the goal of having a prolonged presence in space, or a colony on Mars or some other world, is full of challenges, including the necessity of growing food. Scientists at Kennedy Advanced Life Support Research are working on the Prototype Lunar/Mars Greenhouse Project to try and meet that challenge.
Many stars show tails that trail behind them like a comet’s tail, supporting the idea that our own Solar System has one too. However, new evidence from NASA’s Cassini, Voyager and Interstellar Boundary Explorer (IBEX) missions suggests that the trailing end of the Solar System may not be stretched out in a long tail.
A supervoid is unlikely to explain a ‘Cold Spot’ in the cosmic microwave background, according to the results of a new survey, leaving room for exotic explanations like a collision between universes.
A research team has devised a plan to make a portion of Mars more Earth-like by slamming an asteroid into it.
This Mars Terraformer Transfer (MATT) concept would create a persistent lake on the Red Planet’s surface in 2036, potentially accelerating Mars exploration, settlement and commercial development, the team said.
Mars has an asteroid entourage, with nine so-called Trojans trailing in its wake. Now it seems these travelling companions all had the same violent beginning: as the innards of a mini-planet, eviscerated in a violent collision. Some remnants may even have been incorporated into the material that became Mars.
On Venus, plumes of superheated rock from near the planet’s core may rise up intermittently, destroy patches of the planet’s surface and create unique crown-shaped geologic features called coronae, a new study finds.
Place yourself at the south pole of Enceladus, the icy moon of Saturn. You are standing on a ridge overlooking a trench a few hundred kilometres long and 2 kilometres wide, parallel to three similar trenches – a linear pattern that planetary scientists call tiger stripes.
Scientists are attempting to identify the amino acids—building blocks that make proteins and support all life on Earth—that might feasibly form the basis of extraterrestrial life. The researchers have analyzed how an assortment of 15 amino acids, some found here on Earth in living organisms and some not found in living organisms on Earth, hold up in the face of extreme conditions found on other planets and moons.
More than 750,000 pieces of dangerous debris are now orbiting Earth and threatening the future of spaceflight, the largest ever conference on space rubbish has heard.

A now famous experiment conducted by chemists Stanley Miller and Harold Urey back in 1952 showed that even if we don’t know for sure how the first living cells formed, at least some of their molecular building blocks could have been produced by simple chemical reactions under conditions on ancient Earth.
