Scientists Say There May Be “Humans” All Over the Universe

Posted by in categories: evolution, space

Imagine, if you will, that future humans manage to travel to other worlds and find… more humans.

According to one University of Cambridge astrobiologist, that scenario may be more likely than you’d think.

In a new interview with the BBC’s Science Focus magazine, an evolutionary palaeobiologist at the institution’s Department of Earth Sciences named Simon Conway Morris declared that researchers can “say with reasonable confidence” that human-like evolution has occurred in other locations around the universe.

“Ghost particles” detected in the Large Hadron Collider for first time

Posted by in categories: particle physics, space

Physicists have detected “ghost particles” in the Large Hadron Collider for the first time. An experiment called FASER picked up telltale signals of neutrinos being produced in particle collisions, which can help scientists better understand key physics.

Neutrinos are elementary particles that are electrically neutral, extremely light and rarely interact with particles of matter. That makes them tricky to detect, even though they’re very common – in fact, there are billions of neutrinos streaming through your body right now. Because of this, they’re often described as ghost particles.

Neutrinos are produced in stars, supernovae, quasars. radioactive decay and from cosmic rays interacting with atoms in the Earth’s atmosphere. It’s long been thought that particle accelerators like the LHC should be making them too, but without the right instruments they would just zip away undetected.

Russia launches new docking node to space station

Posted by in categories: futurism, space

Roscosmos launched a new docking node module to the International Space Station (ISS) on Wednesday, November 24 at 13:06 UTC / 8:06 am EST.

Launching from the Baikonur Cosmodrome in Kazakhstan, the module will add additional docking ports to the Russian Segment of the station to provide options for future expansion but is the final Russian model planned for the outpost.

NASA’s Curiosity rover sends a ‘picture postcard’ from Mars

Posted by in categories: robotics/AI, space

NASA’s Curiosity rover has marked the 10th anniversary of its launch to Mars by sending back a spectacular ‘picture postcard’ from the Red Planet.

The robotic explorer snapped two black and white images of the Martian landscape which were then combined and had colour added to them to produce the remarkable composite.

Why we need to return to Uranus and Neptune

Posted by in category: space

As Neptune and Uranus could solve the mysteries of planet formation, we need to go back and study them in depth.

Sending a spacecraft to study Uranus and Neptune could give planetary scientists better clues about the formation of ice giants.

On-chip frequency shifters in the gigahertz range could be used in next generation quantum computers and networks

Posted by in categories: computing, internet, quantum physics, space

The ability to precisely control and change properties of a photon, including polarization, position in space, and arrival time, gave rise to a wide range of communication technologies we use today, including the Internet. The next generation of photonic technologies, such as photonic quantum networks and computers, will require even more control over the properties of a photon.

One of the hardest properties to change is a photon’s color, otherwise known as its frequency, because changing the frequency of a photon means changing its energy.

Today, most frequency shifters are either too inefficient, losing a lot of light in the , or they can’t convert light in the gigahertz range, which is where the most important frequencies for communications, computing, and other applications are found.
