Timeline of the Milky Way

Posted by in category: cosmology

We live in the Milky Way galaxy, an immense, flat, spiral galaxy surrounded by a massive halo of stars and dark matter. The disk of stars, gas, and dust in which the Sun resides is fully 120,000 light years across; a soul-crushing distance on the human scale. In the middle of the disk is the central bulge, a lozenge-shaped hub of stars.

How did all this structure come together? We know it didn’t all happen at once, but what were the different chapters in the galaxy’s life? What is the timeline of the Milky Way?

‘Dead’ telescope discovers Jupiter’s twin from beyond the grave

Posted by in categories: physics, space

NASA’s Kepler space telescope has spotted a Jupiter look-alike in a new discovery, even though the instrument stopped operations four years ago.

An international team of astrophysicists using NASA’s Kepler space telescope, which ceased operations in 2018, have discovered an exoplanet similar to Jupiter located 17,000 light-years from Earth, making it the farthest exoplanet ever found by Kepler. The exoplanet, officially designated K2-2016-BLG-0005Lb, was spotted in data captured by Kepler in 2016. Throughout its lifetime, Kepler observed over 2,700 now-confirmed planets.

Compound From Cardamom Spice Can Kill Aggressive Triple-Negative Breast Cancer Cells

Posted by in category: biotech/medical

Study shows that compound from cardamom shows promise for treating aggressive breast cancer.

Cardamonin — a natural compound found in the spice cardamom and other plants — could have therapeutic potential for triple-negative breast cancer, according to a new study using human cancer cells. The findings also show that the compound targets a gene that helps cancer cells elude the immune system.

About 10–15% of breast cancers are triple-negative, which means they don’t have receptors for estrogen or progesterone and don’t make excess amounts of a protein called HER2. These tumors are difficult to treat because they don’t respond to the hormone-based therapies used for other types of breast cancer. They also tend to be more aggressive and have a higher mortality rate than other breast cancers.

Galactic Beacon—Scientists Propose Sending Revealing Message To Alien Civilizations

Posted by in category: alien life

The brand new “Beacon in the Galaxy” is a binary message created by scientists as an update to the old Arecibo message.


The newly proposed “A Beacon in the Galaxy”, a binary message created by scientists as an update to the old Arecibo message, might actually be more dangerous for us than beneficial. It includes key information about us – our location, our DNA structure, and even an image of the naked human body.

Should we give aliens such vital details about Earth and humanity? This question has been around for ages and countless renowned scientists have expressed their concerns in the past. Even Stephen Hawking explained that a hypothetical alien civilization could be hostile.

Could Artificial Intelligence ever Surpass Humans?

Posted by in categories: ethics, information science, robotics/AI

The battle between artificial intelligence and human intelligence has been going on for a while not and AI is clearly coming very close to beating humans in many areas as of now. Partially due to improvements in neural network hardware and also improvements in machine learning algorithms. This video goes over whether and how humans could soon be surpassed by artificial general intelligence.

Posted by in category: futurism

AUSTIN (KXAN) — At 12 years old, Deep Hayer is already gearing up for college at Austin Community College.

“His understanding of life was much more mature than his peers,” said Rosie Hayer, his mother.

At a young age, Deep’s parents noticed his maturity and his love for learning. In the first grade, he was reading at a seventh-grade level.

BREAKING: Tesla CEO Elon Musk is set to be appointed to Twitter’s board of directors after he revealed he held a 9.2 percent stake in Twitter, which is the largest of any outside shareholder.


Twitter will appoint Tesla CEO Elon Musk to its board of directors, the company announced Tuesday.

As long as Musk is serving on the board, and for 90 days after, he will not be able to own more than 14.9 percent of Twitter’s stock, Twitter said in a Securities and Exchange Commission filing. Musk’s term on the board will expire at the social media company’s 2024 annual meeting of stockholders.

Second Successful Flight for DARPA Hypersonic Air-breathing Weapon Concept (HAWC)

Posted by in category: military

DARPA and its U.S. Air Force partner recently completed a free flight test of the Lockheed Martin version of the Hypersonic Air-breathing Weapon Concept (HAWC). The vehicle, after release from a carrier aircraft, was boosted to its Aerojet Rocketdyne scramjet engine ignition envelope. From there, it quickly accelerated to and maintained cruise faster than Mach 5 (five times the speed of sound) for an extended period of time. The vehicle reached altitudes greater than 65,000 feet and flew for more than 300 nautical miles.

This is the second successful flight in DARPA’s HAWC program. Last September, a different vehicle configuration from another contractor team also reached hypersonic flight.

“This Lockheed Martin HAWC flight test successfully demonstrated a second design that will allow our warfighters to competitively select the right capabilities to dominate the battlefield,” said Andrew “Tippy” Knoedler, HAWC program manager in DARPA’s Tactical Technology Office. “These achievements increase the level of technical maturity for transitioning HAWC to a service program of record.”
