Aurora over Clouds

Auroras usually occur high above the clouds. The auroral glow is created when fast-moving particles ejected from the Sun impact the Earth's magnetosphere, from which charged particles spiral along the Earth's magnetic field to strike atoms and molecules high in the Earth's atmosphere. An oxygen atom, for example, will glow in the green light commonly emitted by an aurora after being energized by such a collision. The lowest part of an aurora will typically occur about 100 kilometers up, while most clouds exist only below about 10 kilometers. The relative heights of clouds and auroras are shown clearly in the featured picture in 2015 from Dyrholaey, Iceland. There, a determined astrophotographer withstood high winds and initially overcast skies in an attempt to capture aurora over a picturesque lighthouse, only to take, by chance, the featured picture including elongated lenticular clouds, along the way.

Top tip. Slow to half speed lol

PS: i also have fallen for his french selections

There are myriad mysteries in the vastness of the universe, but astronomers around the world are particularly enamored with Fast Radio Bursts (FRB) right now. Since discovering the first FRB in the early 2000s, scientists have been trying to identify the source of these intensely powerful electromagnetic signals. ... A new analysis from NASA has traced the origin of several FRBs back to their home galaxies, which could help scientists narrow down a cause.

Mike Rothschild, the author of the new book “The Storm Is Upon Us,” is very concerned about QAnon’s “true believers.” The FBI agrees.

The analysis detected the following 11 alarmingly dangerous pathogens on the masks:

• Streptococcus pneumoniae (pneumonia)

• Mycobacterium tuberculosis (tuberculosis)

• Neisseria meningitidis (meningitis, sepsis)

• Acanthamoeba polyphaga (keratitis and granulomatous amebic encephalitis)
...
• Acinetobacter baumanni (pneumonia, blood stream infections, meningitis, UTIs— resistant to antibiotics)

• Escherichia coli (food poisoning)

• Borrelia burgdorferi (causes Lyme disease)

• Corynebacterium diphtheriae (diphtheria)

• Legionella pneumophila (Legionnaires' disease)

• Staphylococcus pyogenes serotype M3 (severe infections—high morbidity rates)

• Staphylococcus aureus (meningitis, sepsis)

Half of the masks were contaminated with one or more strains of pneumonia-causing bacteria. One-third were contaminated with one or more strains of meningitis-causing bacteria. One-thi

What should be the perfect opening to England’s European Championship campaign — in its home stadium on a scorching summer afternoon — instead carries an element of trepidation about the reception the players will receive from their own fans.

Thousands of jack fish swimming together at Cabo Pulmo National Park, Sea of Cortez, Baja California, Mexico

To celebrate World Oceans Day, we're swimming through a shoal of jack fish just off the coast of Baja, California, in Cabo Pulmo National Park. This Mexican marine park in the Sea of Cortez is home to the northernmost and oldest coral reef on the west coast of North America, estimated to be about 20,000 years old. Jacks are clearly plentiful here, but divers and snorkelers in Cabo Pulmo can also come across many other species of fish and marine mammals, including several varieties of sharks, whales, dolphins, tortoises, and manta rays.
... For this year's World Oceans Day, the UN chose the theme 'The Ocean: Life & Livelihoods,' to raise awareness of the nearly 3 billion people worldwide who depend on oceans for their food and way of life. The residents of Cabo Pulmo know a little about this—to help revitalize their previously unprotected and overfished waters, the Mexican government made Cabo Pulmo a national park in 1995. But more controversially, officials also banned fishing, a big deal in an area where many people lived off the food they caught by hand. The preservation efforts paid off, though—researchers say the park experienced a 460% increase in the number of fish living in park waters between 1999 and 2009, turning Cabo Pulmo into one of the world's most robust marine reserves. Now, many residents who once relied on fishing have been able to move into jobs in ecotourism or other vocations supporting the park.

A Distorted Sunrise Eclipse

Yes, but have you ever seen a sunrise like this? Here, after initial cloudiness, the Sun appeared to rise in two pieces and during partial eclipse, causing the photographer to describe it as the most stunning sunrise of his life. The dark circle near the top of the atmospherically-reddened Sun is the Moon -- but so is the dark peak just below it. This is because along the way, the Earth's atmosphere had an inversion layer of unusually warm air which acted like a gigantic lens and created a second image. For a normal sunrise or sunset, this rare phenomenon of atmospheric optics is known as the Etruscan vase effect. The featured picture was captured in December 2019 from Al Wakrah, Qatar. Some observers in a narrow band of Earth to the east were able to see a full annular solar eclipse -- where the Moon appears completely surrounded by the background Sun in a ring of fire. The next solar eclipse, also an annular eclipse for well-placed observers, will occur later this week on June 10.
