It’s Official: Voyager 2 Has Entered Interstellar Space
Posted by Genevieve Klien in category: alien life
A human-made object has entered the space between the stars for the second time in history, scientists report.
NASA will announce the details live at a press conference today at 11 a.m. ET, at the meeting of the American Geophysical Union (AGU) in Washington. You can watch the press conference live here.

The 8-dimensional space that must be searched for alien life
Posted by Michael Lance in categories: alien life, mathematics
A new mathematical model suggests that signs of extraterrestrial intelligence could be common, for all we know—we’ve barely begun investigating the vastness where they might lie.

Chaos Makes the Multiverse Unnecessary
Posted by Xavier Rosseel in categories: alien life, mathematics, supercomputing
Scientists look around the universe and see amazing structure. There are objects and processes of fantastic complexity. Every action in our universe follows exact laws of nature that are perfectly expressed in a mathematical language. These laws of nature appear fine-tuned to bring about life, and in particular, intelligent life. What exactly are these laws of nature and how do we find them?
The universe is so structured and orderly that we compare it to the most complicated and exact contraptions of the age. In the 18th and 19th centuries, the universe was compared to a perfectly working clock or watch. Philosophers then discussed the Watchmaker. In the 20th and 21st centuries, the most complicated object is a computer. The universe is compared to a perfectly working supercomputer. Researchers ask how this computer got its programming.
How does one explain all this structure? Why do the laws seem so perfect for producing life and why are they expressed in such exact mathematical language? Is the universe really as structured as it seems?

How scientists are working together to solve one of the universe’s mysteries
Posted by Genevieve Klien in categories: alien life, physics
All of these facts may make it sound as though scientists know a lot about Fast Radio Bursts. In reality, we don’t. For instance, though we know they’re not from our galaxy, we don’t know where exactly they come from. We don’t know what causes them. And we’re not sure whether they might be useful as cosmological standards to measure the large scale properties of our universe.
Dozens of theories about Fast Radio Bursts have been proposed. Some conform to standard physics. Others are more exotic, including cosmic strings – hypothetical, one-dimensional structures formed in the early universe – or even rather bizarre: one theory suggests that aliens are responsible.
Now, in an attempt to discover the truth about Fast Radio Bursts, we have created a catalogue that lists each theory, along with its pros and cons. Scientists from around the world can weigh in, and new data and discoveries will be added throughout the process.

‘Solar Gravity Lens’ Could Bring Exoplanets into Sharp Focus
Posted by Genevieve Klien in categories: alien life, innovation
An innovative deep-space concept that relies on a solar gravity lens (SGL) to enable enhanced viewing of exoplanets is under study by researchers at NASA’s Jet Propulsion Laboratory (JPL) and The Aerospace Corporation.
The SGL would provide 100-billion-fold optical magnification, allowing it to show details as small as 6 miles (10 kilometers) across — similar to being able to spot something the size of New York City on an exoplanet, study team members said.
As detailed in a press statement from The Aerospace Corporation, according to Einstein’s theory of relativity, light traveling through space will bend if it passes near sufficiently massive objects. This means that distant light will bend around the periphery of the sun, eventually converging toward a focal region as if it had passed through a lens. [13 Ways to Hunt Intelligent Aliens].
Can you craft a message to be understood by aliens?
The main goal of this activity is to educate the youth on Radio Astronomy techniques and Exoplanetary cutting-edge science, presenting the uniqueness of the Arecibo Observatory capability and raising the awareness of the possible risks involved on messaging unknown earthlings (through social medias) or extraterrestrial civilizations (through radio waves).
Diverse, inter-generation, multi-disciplinary and international teams of 10 students + 1 mentor (professor/scientist/teacher) will have to design the NEW Arecibo message. To unlock the call, register the teams and access the references and specifications for the project, the students will have first to learn about scientific method, AO activities, space sciences and peaceful uses of space issues for, then, be able to break coded messages, solve brain-puzzles and design their new Arecibo Message version.
