'We had to saw off the stake from the front and the back to make it more manageable. We bandaged her up and transported her to the hospital,' Keddy said. The victim, conscious throughout the ordeal, was taken to the Jersey Shore University Medical Centre in Neptune. 'When we dropped her off, she was conscious and alert and in good spirits — all things considered,' Keddy added. There is still no accurate way of knowing how the accident happened. One reason that has been put forward is that the woman might have been attempting to get or pick up an umbrella that had been snagged by a strong wind blast when she fell on the stake.

Dwarf galaxy glows red in the Hunting Dogs constellation
When you buy through links on our articles, Future and its syndication partners may earn a commission. Deep in the constellation Canes Venatici, also called the Hunting Dogs, lies the dwarf galaxy NGC 4449. It's part of the M94 galaxy group, near a group of galaxies to which our Milky Way belongs. In this image, the Hubble Space Telescope recently captured the brilliant red dust and gas clouds swirling in space. NGC 4449 is classified as a dwarf galaxy, as it is much smaller and contains fewer stars than our Milky Way galaxy. A previous photo of NGC 4449, taken by the Hubble Space Telescope, was released in 2007 but this updated version adds new wavelengths of light based on detailed observations made by the telescope, giving further insight into how NGC 4449 formed. With these additional wavelengths, astronomers have found that while NGC 4449 might be a smaller galaxy, it is acting as a powerful stellar nursery. The Hunting Dogs constellation, which hosts the NGC 4449 dwarf galaxy, lies 12.5 million light-years away, according to the European Space Agency (ESA). What NGC 4449 lacks in size, it's making up for in its powerful production of new stars. According to ESA, this dwarf galaxy is churning out stars at a much faster rate than expected for its size. This classifies it as a starburst galaxy. While most starburst galaxies focus star production in their centers, NGC 4449 has new stars forming throughout, possibly due to its interaction with other nearby galaxies. Thanks to its close proximity to Earth, the Hubble Space Telescope can more easily study how interactions between close galaxies influence how new stars are made. You can read more about images taken by the Hubble and starburst galaxies as we continue to peer deep into the far reaches of our universe.

For first time, Webb telescope discovers an alien planet
By Will Dunham WASHINGTON (Reuters) -In addition to providing a trove of information about the early universe, the James Webb Space Telescope since its 2021 launch has obtained valuable data on various already-known planets beyond our solar system, called exoplanets. Now, for the first time, Webb has discovered an exoplanet not previously known. Webb has directly imaged a young gas giant planet roughly the size of Saturn, our solar system's second-largest planet, orbiting a star smaller than the sun located about 110 light-years from Earth in the constellation Antlia, researchers said. A light-year is the distance light travels in a year, 5.9 trillion miles (9.5 trillion km). Most of the roughly 5,900 exoplanets discovered since the 1990s have been detected using indirect methods, such as through observation of the slight dimming of a star's light when a planet passes in front of it, called the transit method. Less than 2% of them have been directly imaged, as Webb did with the newly identified planet. While this planet is large when considered in the context of our solar system, it is actually the least massive one ever discovered through direct imaging - 10 times less massive than the previous record holder. This speaks to the sensitivity of Webb's instruments. This discovery was achieved using a French-produced coronagraph, a device that blocks out the bright light from a star, installed on Webb's Mid-Infrared Instrument, or MIRI. "Webb opens a new window - in terms of mass and the distance of a planet to the star - of exoplanets that had not been accessible to observations so far. This is important to explore the diversity of exoplanetary systems and understand how they form and evolve," said astronomer Anne-Marie Lagrange of the French research agency CNRS and LIRA/Observatoire de Paris, lead author of the study published on Wednesday in the journal Nature. The planet orbits its host star, called TWA 7, at a distance about 52 times greater than Earth's orbital distance from the sun. To put that in perspective, our solar system's outermost planet Neptune orbits about 30 times further from the sun than Earth. The transit method of discovering exoplanets is particularly useful for spotting those orbiting close to their host star rather than much further out like the newly identified one. "Indirect methods provide incredible information for planets close to their stars. Imaging is needed to robustly detect and characterize planets further away, typically 10 times the Earth- to-sun distance," Lagrange said. The birth of a planetary system begins with a large cloud of gas and dust - called a molecular cloud - that collapses under its own gravity to form a central star. Leftover material spinning around the star in what is called a protoplanetary disk forms planets. The star and the planet in this research are practically newborns - about 6 million years old, compared to the age of the sun and our solar system of roughly 4.5 billion years. Because of the angle at which this planetary system is being observed - essentially looking at it from above rather than from the side - the researchers were able to discern the structure of the remaining disk. It has two broad concentric ring-like structures made up of rocky and dusty material and one narrow ring in which the planet is sitting. The researchers do not yet know the composition of the planet's atmosphere, though future Webb observations may provide an answer. They also are not certain whether the planet, being as young as it is, is still gaining mass by accumulating additional material surrounding it. While this planet is the smallest ever directly imaged, it is still much more massive than rocky planets like Earth that might be good candidates in the search for life beyond our solar system. Even with its tremendous capabilities of observing the cosmos in near-infrared and mid-infrared wavelengths, Webb is still not able to directly image Earth-sized exoplanets. "Looking forward, I do hope the projects of direct imaging of Earth-like planets and searches for possible signs of life will become a reality," Lagrange said.

NASA's James Webb Space Telescope uncovers mysterious ‘climate system' on Pluto regulated by strange blue haze
Source: Live Science NASA 's James Webb Space Telescope is again on its way to expand the understanding of the outer solar system. And this time, the explanation on its dwarf planet Pluto that keeps defying expectations. Nearly a decade earlier, NASA's New Horizons spacecraft shattered the notion of the upended assumptions about Pluto's lifelessness, where new data revealed by JWST confirms something extraordinary. One of the biggest surprises which floated above all is Pluto's blueish haze, which isn't just a visual marvel but actively regulates the planet's climate. With James Webb Space Telescope data-gathering in full swing, astronomers hope to study other hazy bodies in the solar system and beyond. The success of this Pluto study may lead to new models of climate formation on exoplanets with thick, layered atmospheres. NASA's James Webb Space Telescope uncovers Pluto's mysterious climate system When NASA's New Horizons spacecraft flew past Pluto in 2015, it shattered the image of Pluto as a dull, frozen rock. Instead, it unveiled a dynamic world marked by vast icy plains, mountain ranges made of water ice, and most intriguingly, a bluish, multi-layered haze that enveloped the planet. This haze extended more than 185 miles (300 km) above Pluto's surface, surprising scientists with its complexity and reach. The discovery hinted that Pluto might have a more active atmosphere than previously believed — but at the time, its true impact remained uncertain. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Giao dịch CFD với công nghệ và tốc độ tốt hơn IC Markets Đăng ký Undo Pluto's haze role in climate regulation revealed Astronomers have now confirmed that Pluto's haze does more than decorate the sky, dedicatedly thanks to the infrared capabilities of JWST. This significantly cools the atmosphere. According to a study published in Nature Astronomy on June 2, this haze absorbs sunlight during the day and releases it as infrared radiation at night, effectively regulating the dwarf planet's temperature. 'This is unique in the solar system,' said Tanguy Bertrand, the study's lead author and an astronomer at the Paris Observatory. 'It's a new kind of climate.' Pluto's haze composition Pluto's haze is composed of complex organic molecules known as tholins, which form when ultraviolet sunlight breaks down methane and nitrogen in the upper atmosphere. These particles then clump together into tiny haze layers that can trap and release heat. Back in 2017, planetary scientists proposed that this haze might be behind Pluto's unusually cold upper atmosphere measured at about -333°F (-203°C), or roughly 30 degrees cooler than models based on gas-only atmospheres had predicted. The idea was compelling, but proving it was another matter entirely. James Webb Space Telescope confirms Pluto's climate theory by separating signals from its Moon One major challenge in confirming the theory was Charon, Pluto's large moon, which orbits so closely that its thermal signal overlaps with Pluto's in most telescope data. This made it nearly impossible to isolate the haze's specific thermal impact. That changed with James Webb Space Telescope. In 2022, its superior infrared resolution allowed researchers to separate the emissions from Pluto and Charon. What they found confirmed the 2017 hypothesis: Pluto's mid-infrared brightness which is caused by its haze and perfectly matched earlier predictions. 'In planetary science, it's not common to have a hypothesis confirmed so quickly,' said Xi Zhang, who led the 2017 study. 'We feel pretty lucky and very excited.' What Pluto's skies reveal about the origins of life on Earth The discovery isn't just a milestone for understanding Pluto but it also opens up new possibilities for studying other hazy celestial bodies. Moons like Titan (Saturn) and Triton (Neptune) are shrouded in their own thick hazes and may exhibit similar atmospheric behaviors. Researchers even suggest that early Earth might have once resembled Pluto. Before oxygen filled our skies, Earth may have had a tholin-rich haze that acted like an insulating blanket, helping stabilize the climate and create conditions that allowed life to evolve. 'By studying Pluto's haze and chemistry,' Zhang said, 'we might get new insights into the conditions that made early Earth habitable.'
