Most of my Forbes essays are meant to be informative pieces on weather, climate, and related sciences. However, there are moments when I use them for editorial commentary. This happens to be one of those moments. While browsing social media this morning, I was reminded of that meteorologists and weather enthusiasts have a habit of
Plasma, that super-hot mix of electrified atomic particles, plays a key role in the evolution of stars, black holes, and other cosmic elements. For closer study though, plasma needs to be recreated in a lab – and researchers have just managed to generate a particular type of plasma jet for the first time. The key
NASA’s Chris Scolese and Gen. Raymond breezed through the hearing where senators praised the nominees’ track records and qualifications for the job. WASHINGTON — “You both will do a great job,” Senate Armed Services Committee Chairman Jim Inhofe (R-Okla.) told Christopher Scolese and Gen. John Raymond on Tuesday at the conclusion of their confirmation hearing.
Mercury is the closest planet to the Sun, so is almost always lost in its glare. But not this month. NASA/Johns Hopkins University Applied Physics Laboratory/Carnegie Institution of Washington If you’ve never seen the tiny planet Mercury, tonight could be your night. The elusive inner planet, which is usually lost in the Sun’s glare, this month becomes
The famous cat-in-a-box thought experiment by Austrian physicist Erwin Schrödinger is an illustration of one of the defining characteristics of quantum mechanics – the unpredictable behaviour of particles at the quantum level. It makes working with quantum systems incredibly difficult; but what if we could make quantum predictions? A team of physicists believes it’s possible.
It was built in the early 12th century by King Suryavarman II, one of the most famous kings of the Angkorian civilization that lasted from approximately the ninth to 15th centuries. The structure is so strongly associated with Cambodian identity even today that it appears on the nation’s flag. For many years, historians placed the
A huge discovery that was incompatible with our current theories of dark matter and galaxy formation may have just been resolved. After a new analysis, astronomers have determined that NGC1052-DF2 – found last year to contain absolutely no dark matter – is a lot closer to us than previous calculations estimated. Which means that it
Strategic Forces subcommittee Chairman Jim Cooper is a Space Force advocate but HASC Chairman Adam Smith publicly has been ambivalent about it. SAN ANTONIO — The House Armed Services Committee subcommittee on strategic forces on Monday released its proposed language to be considered in the National Defense Authorization Act for Fiscal Year 2020. The bill
The inside of the LHC, where protons pass each other at 299,792,455 m/s, just 3 m/s shy of the speed of light. As powerful as the LHC is, the cancelled SSC could have been three times as powerful, and may have revealed secrets of nature that are inaccessible at the LHC. CERN At a fundamental
The first film of a total solar eclipse has been restored by specialists at the British Film Institute (BFI) and made available for viewing. The film was taken in North Caroline in 1900 by Nevil Maskelyne. Maskelyne was a British man who was a magician turned film-maker. He took the film as part of a
SAN ANTONIO — The National Reconnaissance Office awarded commercial imagery study contracts to BlackSky Global, Maxar Technologies and Planet, Troy Meink, who leads NRO’s Geospatial Intelligence Directorate, announced June 3. If all goes as planned, procurement contracts could follow in six to 12 months, he said at the 2019 GEOINT Symposium here. The National Geospatial

There’s a giant contradiction in the middle of the Arizona desert: an experimental city designed for thousands that now contains only a few dozen inhabitants. For nearly five decades, a group called the Cosanti Foundation has been working to build a city that would inspire a new future of urban design. Today, the project is
LONDON (Reuters) – A rogue Chinese scientist who caused outrage last year when he said he had created the world’s first “gene-edited” babies in an attempt to protect them from HIV may also have put them at risk with a “foolish” choice of gene, experts said on Monday.

NGA Director Vice Adm. Robert Sharp said the agency needs to change its business practices. SAN ANTONIO, Texas — In the data arms race, it’s not about how much data you have but what you do with it. That about sums up the challenge facing the National Geospatial Intelligence Agency (NGA), a giant organization of

You’re sitting an exam, and just can’t recall the answer you know is in your brain somewhere. A new study suggests that a quick zap to a region in your prefrontal cortex might help you find the missing memory. Okay, so maybe using this in practice is more science fiction than science at this stage,
Death, for stars, isn’t always a straightforward affair. In fact, it can get downright weird. Astronomers have just identified a star made from the remnants of two dead stars that fused together, which reignited fusion in the core – bringing the new star back to life. The star is called J005311, 10,000 light-years away in
Twitter, used by 126 million people daily and now ubiquitous in some industries, has vowed to reform itself after being enlisted as a tool of misinformation and hate. But new evidence shows that the platform may be inflicting harm at an even more basic level. It could be making its users, well, a bit witless.
WASHINGTON — NASA is suffering growing problems with cost and schedule on its major programs, driven by continued issues with two of its highest profile efforts. In its annual “Assessments of Major Projects” report issued May 30, the Government Accountability Office found that average cost growth and schedule delay for large NASA programs grew in
