Extreme Ocean Temperatures are Affecting Florida’s Coral Reefs | NOAA

Extreme Ocean Temperatures are Affecting Florida’s Coral Reefs | NOAA

Since April 2023, the National Oceanic and Atmospheric Administration (NOAA) has been monitoring a steady rise in ocean temperatures, which is resulting in unprecedented heat stress conditions in the Caribbean basin, including waters surrounding Florida and the Gulf of Mexico. On Thursday, August 17, 2023, NOAA scientists provided a briefing on how these record-breaking warm ocean temperatures have stressed, bleached, and in some cases, killed corals within the 3,800 square miles of the Florida Keys National Marine Sanctuary.

Florida Keys National Marine Sanctuary

https://floridakeys.noaa.gov

Florida is a state in the Southeastern region of the United States, bordered to the west by the Gulf of Mexico; Alabama to the northwest; Georgia to the north; the Bahamas and Atlantic Ocean to the east; and the Straits of Florida and Cuba to the south. It is the only state that borders both the Gulf of Mexico and the Atlantic Ocean.

Coral reefs are often referred to as the "rainforests of the sea," due to their incredible biodiversity and ecological importance. They provide vital benefits as part of marine ecosystems by sustaining habitats for marine life, buffering the harmful impacts of storms on coastal communities, and supporting local economies through tourism and fishing.

India's Chandrayaan-3 Lunar Lander Mission: First Close-up Moon Images | ISRO

The Indian Space Research Organisation (ISRO) Chandrayaan-3 Lunar Mission captured images of the Moon during Lunar Orbit Insertion (LOI) and after the separation of the lunar lander from the propulsion module. Chandrayaan-3, ISRO’s third lunar exploration mission, consists of a propulsion module, a lander, and a rover. Chandrayaan-3 is planned to land about 70.9 degrees south of the lunar equator. Chandrayaan-3 is India's effort to become the fourth country, after the United States, Russia and China, to successfully soft-land on the Moon. The Chandrayaan-3 spacecraft would also be the first to land at the lunar south pole, an area of special interest for space agencies and private space companies because of the presence of water ice that could support future surface activities.

The Boogeyman Nebula: LDN 1622 in Orion | Schulman Telescope

The Boogeyman Nebula: LDN 1622 in Orion | Schulman Telescope

To some, this dark shape looks like a mythical boogeymana mythical creature used by adults to frighten children into good behavior. Scientifically, Lynds' Dark Nebula (LDN) 1622 appears against a faint background of glowing hydrogen gas only visible in long telescopic exposures of the region. LDN 1622 lies near the plane of our Milky Way Galaxy, close in the sky to Barnard's Loop, a large cloud surrounding the rich complex of emission nebulae found in the Belt and Sword of Orion.

 LDN 1622 is a dark nebula, so called because these dense interstellar clouds of gas and dust blot out light from background objects, appearing as ink-dark clouds against a backdrop of stars. This enigmatic cosmic cloud is 1,300 light-years from Earth in the nearby Orion complex, a star-forming region thronging with young stars and other dark nebulae.

Gravitational Waves: Ripples in Space-Time | Hubble Science | NASA Goddard

Gravitational Waves: Ripples in Space-Time | Hubble Science | NASA Goddard

Gravitational waves are invisible ripples in the fabric of space-time. They are caused by some of the most violent and energetic events in the universe. These include colliding black holes, collapsing stellar cores, merging neutron stars or white dwarf stars, the wobble of neutron stars that are not perfect spheres and possibly even the remnants of gravitational radiation created by the birth of the universe.

In this video, Dr. Padi Boyd explains gravitational waves and how important the Hubble Space Telescope is to exploring the mysteries of the universe.

HD 45166: The Most Magnetic Massive Star Found | Artist’s Animation | ESO

HD 45166: The Most Magnetic Massive Star Found | Artist’s Animation | ESO

This video shows an artist’s animation of HD 45166, a massive star recently discovered to have a powerful magnetic field of 43,000 gauss, the strongest magnetic field ever found in a massive star. Intense winds of particles blowing away from the star are trapped by this magnetic field, enshrouding the star in a gaseous shell as illustrated here.

This finding provides clues to the origin of magnetars, compact dead stars laced with magnetic fields at least a billion times stronger than the one in HD 45166. Astronomers believe that this star will end its life as a magnetar. As it collapses under its own gravity, its magnetic field will strengthen, and the star will eventually become a very compact core with a magnetic field of around 100 trillion gauss—the most powerful type of magnet in the Universe.

HD 45166 is part of a binary system. In the background, we get a glimpse of HD 45166’s companion, a normal blue star that has been found to orbit at a far larger distance than previously reported.

New Type of Massive Magnetic Helium Stars Gives Clues to Magnetars’ Origins | ESO

New Type of Massive Magnetic Helium Stars Gives Clues to Magnetars’ Origins | ESO

ESOcast 264 Light: Using multiple telescopes around the world, including European Southern Observatory (ESO) facilities, researchers have uncovered a living star that is likely to become a magnetar, an ultra-magnetic dead star that is a variant of neutron stars. This video summarizes the discovery. Magnetars are the strongest magnets in the Universe. These super-dense dead stars with ultra-strong magnetic fields can be found all over our galaxy but astronomers do not know exactly how they form. This finding marks the discovery of a new type of astronomical object—massive magnetic helium stars—and sheds light on the origin of magnetars.

Despite having been observed for over 100 years, the enigmatic nature of the star HD 45166 could not be easily explained by conventional models, and little was known about it beyond the fact that it is one of a pair of stars, is rich in helium and is a few times more massive than our Sun. HD 45166 is located about 3,000 light-years away in the constellation Monoceros (the Unicorn). This star was discovered to have an incredibly strong magnetic field, of 43,000 gauss, making HD 45166 the most magnetic massive helium star found to date.

In a few million years, HD 45166 will explode as a very bright, but not particularly energetic, supernova. During this explosion, its core will contract, trapping and concentrating the star’s already daunting magnetic field lines. The result will be a neutron star with a magnetic field of around 100 trillion gauss—the most powerful type of magnet in the Universe.

Neutron stars, the compact remains of a massive star following a supernova explosion, are the densest matter in the Universe. Some neutron stars, known as magnetars, also claim the record for the strongest magnetic fields of any object. How magnetars, which are a mere 15 kilometers across, form and produce such colossal magnetic fields remains a mystery.

Russia's Luna-25 South Pole Lander: First Close-up Moon Image

Russia's Luna-25 South Pole Lander: First Close-up Moon Image

[No Audio] Russia's Luna-25 lunar lander mission captured an image of the Zeeman crater located on the Moon's far side, near its south pole, on August 17, 2023. Zeeman crater is not directly visible from the Earth. Russia launched an uncrewed spacecraft, called Luna-25, Friday, Aug. 11, 2023, designed to land on the south pole of the Moon—the country's first robotic lunar mission since 1976. Russia seeks to become the first nation to make a soft landing on the Moon’s icy south pole. 

Luna-25 will attempt a soft landing on the lunar surface, north of the Boguslawsky crater, on Aug. 21, 2023, according to Roscosmos. Boguslawsky is a lunar impact crater that is located near the Moon's southern lunar limb.

This timetable puts Russia in a race with India, which launched a similar mission—the Chandrayaan-3 lunar lander—last month and is aiming to soft-land on the Moon's south pole by Aug. 23. “We hope to be first,” Roscosmos chief Yuri Borisov reportedly said at Luna-25's launch.

Borisov, director general of Roscosmos, hailed the Aug. 21 launch as a “new page” for Russian space exploration. “All the results of the research will be transferred to Earth,” he said on state television. “We are interested in the presence of water, as well as many other experiments related to the study of the soil, the site.” He noted that the mission is bound to face some “obstacles” along the way.

Planet Neptune’s Disappearing Clouds Linked to the Solar Cycle | Hubble

Planet Neptune’s Disappearing Clouds Linked to the Solar Cycle | Hubble

Recent observations from the Hubble Space Telescope show that Neptune's clouds are almost completely disappearing! Astronomers report that their continual monitoring of Neptune’s weather uncovered a link between its shifting cloud abundance and the 11-year solar cycle, where the Sun’s activity waxes and wanes under the driving force of its entangled magnetic field. 

At present, the cloud coverage seen on Neptune is extremely low, with the exception of some clouds hovering over the giant planet’s south pole. A team of astronomers discovered that the abundance of clouds normally seen at the icy giant’s mid-latitudes started to fade in 2019.

Planet Neptune's Cloud Cover over Three Decades: Linked to Solar Cycle | Hubble

Planet Neptune's Cloud Cover over Three Decades: Linked to Solar Cycle | Hubble


This sequence of Hubble Space Telescope images chronicles the waxing and waning of the amount of cloud cover on Neptune. This long set of observations shows that the number of clouds grows increasingly following a peak in the solar cycle—where the Sun's level of activity rhythmically rises and falls over an 11-year period. The chemical changes are caused by photochemistry, which happens high in Neptune's upper atmosphere and takes time to form clouds.

The images reveal an intriguing pattern between seasonal changes in Neptune’s cloud cover and the solar cycle—the period when the Sun's magnetic field flips every 11 years as it becomes more tangled like a ball of yarn. This is evident in the increasing number of sunspots and increasing solar flare activity. As the cycle progresses, the Sun’s tempestuous behavior builds to a maximum, until the magnetic field beaks down and reverses polarity. Then the Sun settles back down to a minimum, only to start another cycle.

When it is stormy weather on the Sun, more intense ultraviolet (UV) radiation floods the solar system. The team found that two years after the solar cycle's peak, an increasing number of clouds appear on Neptune. The team further found a positive correlation between the number of clouds and the ice giant's brightness from the sunlight reflecting off it.

The link between Neptune and solar activity is surprising to planetary scientists because Neptune is our solar system's farthest major planet and receives sunlight with about 0.1% of the intensity Earth receives. Yet Neptune's global cloudy weather seems to be driven by solar activity, and not the planet's four seasons, which each last approximately 40 years.

In 1989, NASA's Voyager 2 spacecraft provided the first close-up images of linear, bright clouds, reminiscent of cirrus clouds on Earth, seen high in Neptune's atmosphere. They form above most of the methane in Neptune's atmosphere and reflect all colors of sunlight, which makes them white. Hubble picks up where the brief Voyager flyby left off by continually keeping an eye on the planet yearly.

The Hubble Space Telescope is a project of international cooperation between NASA and the European Space Agency (ESA). NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy, in Washington, D.C.

A Giant in Moonlight: The Extremely Large Telescope (ELT) under Construction

A Giant in Moonlight: The Extremely Large Telescope (ELT) under Construction

This image shows the Extremely Large Telescope (ELT) construction site in the Atacama desert of Chile in South America, kissed by the white moonlight that fills the air. Although the Moon itself is not in the frame, you can feel its presence nearby. The night sky is a deep blue, becoming slightly whiter as it meets the brown horizon of the desert. Dominating the center of the image is the giant ELT structure under construction, with its circular concrete base at the bottom and its magnificent steel-framed dome on top. The criss-cross steel frame now has two complete arches at the top. On the right and left of the ELT are two cranes leaning in towards the telescope.

It is now close to 80 meters high—the mammoth steel structure of the European Southern Observatory’s Extremely Large Telescope (ELT) dome is taking shape in this image, taken on August 2, 2023, under the light of the full Moon. Right now, engineers and construction workers are assembling the structure of the telescope dome in the Chilean Atacama Desert, with progress visible almost every day. When completed, the ELT will be the world’s biggest eye on the sky for visible and infrared observations.

Overall, the ELT project is now more than 50 percent complete. The dome structure visible here will house a pioneering five-mirror optical design, which includes a giant main mirror (M1), 39 meters wide and made up of 798 hexagonal segments. The telescope mirrors and other components are being built by companies in Europe, where work is progressing well too. All of the other systems needed to complete the ELT, including the control system and the equipment needed to assemble and test the telescope, are also coming along nicely.

When finished, the dome will weigh in at 6100 tonnes, and it will need a mind-boggling 30 million bolts to be held together. This huge structure will shelter the telescope during observations, protecting it from the elements. The entire behemoth will rotate on 36 stationary trolleys, allowing astronomers to observe the southern sky from just about any direction they fancy.

The current largest optical telescopes have diameters of up to ten meters, and the ELT's diameter will thus be four times greater. This diameter was chosen because it is the minimum diameter needed to achieve some of the driving science cases. For example, the ELT will be able to image rocky exoplanets and to characterize their atmospheres, while the existing ESO Very Large Telecope (VLT) can only indirectly detect such Earth-like planets. Moreover, the ELT will be able to directly measure the acceleration of the expansion of the Universe. Adaptive optics systems are fully incorporated into the design of the telescope to compensate for the fuzziness in the stellar images introduced by atmospheric turbulence. The ELT will have more than 5,000 actuators that can change the shape of its mirrors a thousand times per second.

Altitude: 3046 meters

Planned year of technical first light: 2027
