Using the James Webb Space Telescope (JWST), astronomers from the Space Telescope Science Institute (STScI) have discovered a new supernova. Designated SN 2023adsy, the newfound stellar explosion is the most distant Type Ia supernova so far detected. The finding was detailed in a research paper published June 7 on the pre-print server arXiv.

Supernovae (SNe) are powerful and luminous stellar explosions. They are important for the scientific community as they offer essential clues into the evolution of stars and galaxies. In general, SNe are divided into two groups based on their atomic spectra: Type I (no hydrogen in their spectra) and Type II (showcasing hydrogen spectral lines).

Type Ia supernovae (SN Ia) are found in binary systems in which one of the stars is a white dwarf. Stellar explosions of this type are important for the scientific community, as they offer essential clues into the evolution of stars and galaxies.

SN 2023adsy was initially identified in 2023 as a transient object in the galaxy JADES-GS+53.13485โˆ’27.82088, at a redshift of 2.9. Follow-up observations of SN 2023adsy suggested that it may be a supernova of Type Ia.

Now, a new study conducted by a team of astronomers led by STScI's Justin R. Pierel confirms the previous assumptions.

Earthquakes may betray their impending presence much earlier than previously thought through a variety of anomalies present in the ground, atmosphere and ionosphere that can be detected using satellites, a recent study in the Journal of Applied Geodesy suggests.

Developing early warning systems for earthquakes could be very helpful in preventing death and destruction. One such proposed technique involves using satellites to monitor a variety of physical and chemical parameters within the ground, atmosphere and the layer of charged particles that exists above it, called the ionosphere.

High-speed baby stars are circling the supermassive black hole Sgr A* like a swarm of bees

Observational astronomy shows that newly discovered young stellar objects (YSOs) in the immediate vicinity of the supermassive black hole Sagittarius A* located in the center of our galaxy behave differently than expected. They describe similar orbits to already known young evolved stars and are arranged in a particular pattern around the supermassive black hole.

Abstract: Since government must be involved in the accumulation of capital to legitimate its activities, and since humans are, in the eyes of government, key resources, government must therefore be involved in activities that manage, control and increase the efficiency of these resources whilst at the same time fostering the spread of business. As we have outlined throughout Parts 1 and 2, history shows evidence of how the transhumanist movement has gained a foothold in society through government and business activities, in accordance with high-level military-intelligence forecasting and scenario planning, and how the global program may be viewed and understood as the only rational response to increasingly outdated humans who, save for the gift of high-tech bio/nano brain-chip upgrades, cannot compete against the machines. These kinds of sentiments, wrong as they are, are reflected in language output, which represents the centre of our thinking. Part 3, thus, introduces aspects of cognitive science as a way of examining more closely how centres of power conceptualise human beings and their environments as containers to be managed and controlled by authorities, and how these conceptualisations appear in language, in policy, and in practice. We make the case that behind the theatre of government, electoral politics and manufactured global crises, transhumanist battle-plans have been consistently enacted in policy and in governance, such that "democratic processes" do little more than provide civilian cover for military operations.


The new Large Binocular Telescope images of Io are so good, it looks like a spacecraft took them

The Large Binocular Telescope (LBT), located on Mount Graham in Arizona and run by the University of Arizona, is part of the next generation of extremely large telescopes (ELTs). With two primary mirrors measuring 8.4 m (~27.5 ft), it has a collecting area slightly greater than that of a 30-meter (98.4 ft) telescope. With their resolution, adaptive optics, and sophisticated instruments, these telescopes are expected to probe deeper into the Universe and provide stunning images of everything from distant galaxies to objects in our Solar System.

An international team led by the University of Arizona recently acquired images of Jupiter's moon Io that were the highest-resolution pictures ever taken by a ground-based telescope. The images revealed surface features measuring just 80 km (50 mi) across, a spatial resolution previously reserved for spacecraft. This includes NASA's Juno mission, which has captured some of the most stunning images of Io's volcanoes. These images were made possible by the LBT's new SHARK-VIS instrument and the telescope's adaptive optics system.


Interstellar cloud hit Earth 3 million years ago

interstellar cloud
Today, Earth is in a safe space. Like all the other planets in the Solar System, it is cocooned within the sun's magnetic field--a giant bubble called "the heliosphere." The heliosphere protects us from dangerous things in the Galaxy like interstellar clouds and cosmic rays.

3 million years ago, the heliosphere may have collapsed. A new paper just published in Nature Astronomy argues that a dense cloud of gas hit the Solar System, compressing the heliosphere to a fraction of its usual size.

"Earth suddenly was outside the protective bubble," says the paper's lead author Merav Opher, a fellow at Harvard Radcliffe Institute and professor at Boston University. "Earth and all the planets were exposed to massive amounts of hydrogen, increased radiation, and interstellar dust."

Comment: As the following articles detail, an event that dramatically shifts Earth's environment could have had a myriad of implications for life on our planet: See also: Mysterious wave-like structure in our galaxy found to be slowly rippling


Scientist working on desperate plan to refreeze Arctic

Deep Freeze

It sounds pretty out-there: to save the snowy Arctic from melting away due to global warming, some scientific experts have been working on plans to hack the entire region's climate.

This doesn't entail popping the North Pole into an unfathomably large deep freezer like so much ground beef, but it would involve a slate of projects โ€” some of which are already being undertaken โ€” to cool the region by reflecting sunlight, according to a new video short from The Wall Street Journal.

One experiment involves pumping water to the surface, where it'll freeze to form a protective layer over the Arctic snow. Another has scientists scattering reflective glass beads on top of snow to reflect the Sun's harsh rays.

These are all forms of geoengineering, techniques to mold certain aspects of the environment in order to offset harm from climate change. The fact we are even seriously contemplating these experiments means that our collective mitigation efforts aren't enough โ€” because last year was the warmest year on record for the Arctic.


Transhumanist Futures, Part 2: Humanity in the Crosshairs

The Transhumanist campaign against humanity, we have outlined in Part 1, is part and parcel of a sophisticated long-game strategy waged against bodies and psyches. With the manipulation of our primal fears and altruistic impulses, the prosecution of this technological onslaught against humanity is camouflaged by linguistic shell games based on sanitising, eulogising and euphemistic language; justification through appeal to valued collective activities such as space exploration; and by claimed threats that humanity is itself the scourge, including through its propensity for "unwanted" love, which is recast as an affliction needing treatment with biochips and neuroceuticals. In this perverse "New Normal", technocratic regimes of dispossession headed by transnational economic interests and, we argue, the military-intelligence complex, are presented as self-evident and morally justified. Social order, civil rights, and human sovereignty are reconceptualised, repackaged, and reframed in public discourse as "surveillance under the skin". Part 2 broadens scope beyond NASA and its purportedly space-oriented transhumanist agenda by offering analysis of transhumanist forecasting and planning in an array of military-intelligence strategic vision or 'futures' documents, which are focused both on military personnel and civilian populations. We reveal that this evidence not only casts military personnel as fodder for transhumanist experimentation, but foresees societies and leadership agendas stratified along transhumanist lines. The trail of documentation ultimately leads to an intersection with military-intelligence scenario planning for a pandemic-ravaged dystopian global landscape in the year 2020, with real and present implications for impending global governance under the World Health Organisation, with ratification of amendments to International Health Regulations and a new Pandemic Preparedness treaty pending in May 2024.


The brain can store nearly 10 times more data than previously thought, study confirms

Scientists harnessed a new method to precisely measure the amount of information the brain can store, and it could help advance our understanding of learning.

The brain may be able to hold nearly 10 times more information than previously thought, a new study confirms.

Similar to computers, the brain's memory storage is measured in "bits," and the number of bits it can hold rests on the connections between its neurons, known as synapses. Historically, scientists thought synapses came in a fairly limited number of sizes and strengths, and this in turn limited the brain's storage capacity. However, this theory has been challenged in recent years โ€” and the new study further backs the idea that the brain can hold about 10-fold more than once thought.

In the new study, researchers developed a highly precise method to assess the strength of connections between neurons in part of a rat's brain. These synapses form the basis of learning and memory, as brain cells communicate at these points and thus store and share information.

By better understanding how synapses strengthen and weaken, and by how much, the scientists more precisely quantified how much information these connections can store. The analysis, published April 23 in the journal Neural Computation, demonstrates how this new method could not only increase our understanding of learning but also of aging and diseases that erode connections in the brain.


A 'new star' could appear in the sky any night now. Here's how to see the Blaze Star ignite

The "Blaze Star" T Coronae Borealis will erupt with a magnificent explosion sometime between now and September, becoming visible to the naked eye. Here's how to find it when it does.

A dim star in the night sky 3,000 light-years from our solar system could soon become visible to the naked eye for the first time since 1946 โ€” and you can easily find it in the night sky.

The "Blaze Star" โ€” officially called T Coronae Borealis (T CrB) โ€” is expected to brighten significantly between now and September 2024 from magnitude +10 (beyond naked-eye visibility) to magnitude +2, according to NASA. That's about the same brightness as Polaris, the North Star, the 48th-brightest star in the night sky. (In astronomy, the brighter an object is, the lower its magnitude; the full moon's magnitude is -12.6, for example).
