Sunspot Activity on The Sun Is Seriously Exceeding Official Predictions

Weather predictions here on Earth are more accurate than they’ve ever been; trying to predict the behavior of our wild and wacky Sun is a little more tricky.

Case in point: according to official predictions, the current cycle of solar activity should be mild. But the gap between the prediction and what’s actually happening is pretty significant – and it’s getting wider. Sunspot counts, used as a measure for solar activity, are way higher than the predicted values calculated by the NOAA, NASA, and the International Space Environmental Service.

In fact, sunspot counts have been consistently higher than predicted levels since September 2020. This could mean that, in contrast to predictions, the Sun is in the swing of an unusually strong activity cycle.

Astronomers detect galactic space laser

A powerful radio-wave laser, called a “megamaser”, has been observed by the MeerKAT telescope in South Africa. The record-breaking find is the most distant megamaser of its kind ever detected, at about five billion light years from Earth.

The light from the megamaser has traveled 58 thousand billion billion (58 followed by 21 zeros) kilometers to Earth. The discovery was made by an international team of astronomers led by Dr. Marcin Glowacki, who previously worked at the Inter-University Institute for Data Intensive Astronomy and the University of the Western Cape in South Africa.

Dr. Glowacki, who is now based at the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR) in Western Australia, said megamasers are usually created when two violently collide in the Universe.

Is Crypto Re-Creating the 2008 Financial Crisis?

What follows is one of the most fascinating and eye-opening conversations I’ve had about crypto. We cover America’s casino mindset, the echoes of the financial crisis she’s sensing right now, how to regulate crypto, and how to innovate without exploiting others. Allen offers a lacerating but level-headed criticism of the space that is well worth your time.

Charlie Warzel: Your essay is about DeFi, or decentralized finance. Like a lot of terminology in the crypto space, DeFi is pretty broad and vague but also very much accepted in the lexicon. How do you define it?

Hilary J. Allen: Like any evolving space, the terminology is hard to pin down. People inside the crypto world have different definitions for DeFi and would probably argue with mine. But the way I think of DeFi is as a way to describe any analogue of traditional financial-service transactions—loans, deposits, etc.—that are provided using technological tools like the blockchain or facilitated through smart contracts or stablecoins. The technology is what is different, but the financial transactions are very much similar to traditional finance.

Physicists Found a Way to Mimic Neutron Stars in the Lab

Using a “laser pincer,” scientists can generate their own antimatter, simulations show.


An international team of physicists have come up with a way to generate antimatter in the lab, allowing them to recreate conditions that are similar to those near a neutron star.

This setup, at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) research laboratory in Germany, involves two high-intensity laser beams that can generate a jet of antimatter, as outlined in a paper published earlier this summer in the journal Communications Physics. That could make antimatter-based research far more accessible for scientists around the world.

Head of U.S. Space Force launch operations ‘watching Starship closely’

Brig. Gen. Stephen Purdy: Seeing Starbase ‘gives you a lot of ideas of what the future could be’

COLORADO SPRINGS – Brig. Gen. Stephen Purdy was in Boca Chica, Texas, last month visiting Starbase. That is SpaceX’s launch and rocket manufacturing and testing facility where the company hopes to operate Starship, the largest rocket ever built.

Purdy is the commander of Florida’s Eastern Range and also serves as the Space Force’s program executive officer for assured access to space, a new post within the Space Systems Command overseeing launch services procurement for the U.S. military and intelligence agencies.
