☆ What are the missiles in Iran’s arsenal and how does Israel counter them?
▼ + stars: | 2024-10-02 | by ( Brad Lendon | Gianluca Mezzofiore | ) edition.cnn.com time to read: +7 min

Here’s a look at Iran’s ballistic missile capabilities and the defensive systems employed by Israeli and other forces in the region. The Shahab-3 is the foundation for all Iran’s medium-range ballistic missiles using a liquid propellant, according to Patrick Senft, a research coordinator at Armament Research Services (ARES). But analysts point out that almost all ballistic missiles reach hypersonic speed during their flights, especially as they dive towards their targets. Some 180 ballistic missiles had been launched from Iran against Israel and intercepted in the sky across Israel on October 1, 2024. Meanwhile, the Arrow 3 uses hit-to-kill technology to intercept incoming ballistic missiles in space, before they reenter the atmosphere on their way to targets.

The second moon that Earth has captured in its orbit this month is an asteroid called 2024 PT5. Mini-moons like this could be ideal targets for asteroid mining to send humans deeper into space. Space mining could be huge, since some asteroids are worth more than our entire global economy. Some startups are trying to figure out how to start mining space rocks, and do it in a cost-effective way. "Either if you are thinking about collecting mineral samples for research or starting a space mining venture, mini-moons are your best bet to get your business off the ground," he said.

☆ Everest grew taller faster after Himalayan river ‘piracy,’ scientists say
▼ + stars: | 2024-09-30 | by ( Mindy Weisberger | ) edition.cnn.com time to read: +8 min

This process, known as river piracy, set in motion a chain of geological events that reshaped the landscape, scientists reported Monday in the journal Nature Geoscience. While some instances of river capture and landscape remodeling began millions of years ago, others are happening today, she added. Evidence of one ancient example still exists around the edges of the Himalayas, where long-ago river capture eroded deep gorges. Han’s simulations suggested that river capture would have dramatically increased the flow of water in the Kosi’s lower segments. Compared with river piracy, erosion and uplift unspool over a much longer time span — and are still happening with Everest, Lhotse and Makalu.

☆ Earth is about to have a temporary ‘mini-moon’

But as a mini-moon, Asteroid 2024 PT5 isn’t in any danger of colliding with Earth now or over the next few decades, de la Fuente Marcos said. Asteroid 2020 CD3 is considered a long-capture mini-moon, while the newly detected Asteroid 2024 PT5 is a short-capture one. Short mini-moon events can occur several times per decade, but long mini-moon events are rare, and only occur every 10 or 20 years, de la Fuente Marcos said. “In order to become a mini-moon, an incoming body has to approach Earth slowly at close range,” de la Fuente Marcos said. After 56.6 days, the sun’s gravitational pull will bring Asteroid 2024 PT5 back into its normal orbit.

Last week, DEEP announced a precursor to the Sentinel, a smaller underwater habitat which the company will use to develop systems for the Sentinel but will also be released as a separate product. An underwater habitat placed on the seabed near the wreck could have served as a base for divers instead, said Wolpert. OAR/National Undersea Research Program (NURP)Aquarius replaced Hydrolab after it was decommissioned. OAR/National Undersea Research Program (NURP)Dennison, of the University of Maryland, said Hydrolab was damp, cramped, lacked indoor plumbing, and had only three beds for four occupants. Wolpert said that DEEP is more than a habitat, it’s also a platform for engaging the next generation.

☆ September’s full harvest supermoon will also create a partial lunar eclipse: How and when to see it
▼ + stars: | 2024-09-17 | by ( Ashley Strickland | ) edition.cnn.com time to read: +5 min

CNN —Sky-gazers around the world will be able to glimpse a partial lunar eclipse while September’s full harvest moon shines brightly Tuesday night. If you’re viewing the moon on Tuesday evening, for about an hour it will also appear as if a bite has been taken out of it due to a partial lunar eclipse. A partial lunar eclipse occurs when Earth moves between the sun and the full moon without being perfectly aligned. During a total lunar eclipse, Earth’s shadow can turn the moon’s surface a striking red color, which is known as a blood moon, according to NASA. The moon is seen through the clouds during a partial lunar eclipse over Caracas, Venezuela, early on November 8, 2022.

A full moon on Tuesday will coincide with a partial lunar eclipse, giving people in North America, South America, Africa and Europe a chance to see part of the moon’s surface obscured by Earth’s shadow. A partial lunar eclipse occurs as Earth passes between the moon and the sun, creating a celestial alignment that blocks sunlight from hitting the lunar surface. It will also be a supermoon, because the moon will be at its closest point to Earth in its elliptical, 27-day orbit. After the peak of the eclipse, the moon will begin exiting Earth’s shadow, ending early Wednesday at around 12:47 a.m. Unlike with solar eclipses, there’s no need to wear protective eyewear when watching a lunar eclipse and it can be viewed safely with the naked eye.

☆ Mega El Niño events may have caused planet’s greatest mass extinction
▼ + stars: | 2024-09-12 | by ( Katie Hunt | ) edition.cnn.com time to read: +8 min

The El Niño of 252 million years ago would have originated in the Panthalassic Ocean, a body of water much larger than today’s Pacific that could hold more heat, which in turn would have strengthened and sustained El Niño effects. The planet had experienced similar episodes earlier but they hadn’t triggered a mass extinction. A prolonged and intense El Niño also explained why extinctions had begun on land before they occurred in the ocean, the study said. This data showed how temperature rose at different latitudes as the mass extinction unfolded. El Niño events today are known to cause coral bleaching and mass mortality of fish, the study noted, but the ecological impact and future trajectory of El Niño events in a warming climate are unknown.

The mission, dubbed Polaris Dawn, was set to take flight as soon as 3:38 a.m. This launch attempt comes after several issues hampered the Polaris Dawn crew’s efforts to get off the ground in late August. Because carrying out a spacewalk will create a drain on oxygen supplies, the Polaris Dawn mission will have only enough life support for five or six days in space. If successful, Polaris Dawn would beat that record by about 20 miles (32 kilometers). Polaris Dawn may also mark the farthest any woman has ever gone into space.

The newly discovered fossils preserved 3D structures within the delicate wing bones, which typically are found flattened like pancakes within rock layers. CT scans of the fossils provided a rare glimpse inside the wing bones belonging to two species of pterosaurs, including one new to science. These are not unlike those found in the wing bones of modern birds that flap their wings to fly, Rosenbach said. In contrast, spiral ridges within Arambourgiania’s wing bones resembled the interiors of vulture wing bones, which are thought to resist the forces associated with soaring. “They represent the largest animals with the capacity to fly,” Rosenbach said of the extinct reptiles.

This affluent coastal city in Southern California, around 30 miles south of Los Angeles, has long enticed people with its Pacific Ocean views and lush greenery. This February, an atmospheric river dumped record amounts of rain across southern California, triggering hundreds of mudslides and leaving at least nine people dead. In July, a landslide triggered by heavy monsoon rains in India’s southern state of Kerala killed at least 150 people. In Southern California, “people wanted to pretend they lived in the tropics,” he said, “and planted a lot of landscaping that required lots of watering.”Deforestation is another factor.

Parts of Canada’s Boreal Forest Are Burning Faster Than They Can Regrow The delicate balance of one the planet’s largest natural systems for storing carbon depends on the humble black spruce tree. The boreal forests are the largest forests in the world, and in Western Canada they evolved to burn once every century or so. What was troubling, Dr. Baltzer noted, is that fire isn’t supposed to make life harder for the black spruce tree. Any imbalance in this tug of war between life and death can threaten the boreal forests’ ability to store heat-trapping carbon. Given how huge the boreal forests are, her research could help shed light on which parts of the ecosystem were most important to protect.
