Explanation: From afar, the whole thing looks like an Eagle. A closer look at the Eagle Nebula, however, shows the bright region is actually a window into the center of a larger dark shell of dust. Through this window, a brightly-lit workshop appears where a whole open cluster of stars is being formed. In this cavity tall pillars and round globules of dark dust and cold molecular gas remain where stars are still forming. Already visible are several young bright blue stars whose light and winds are burning away and pushing back the remaining filaments and walls of gas and...

This has been one far-out year! UFO sightings across the city are up 31% from last year — 46, compared with 35 — and an eye-popping 283% from 2018’s measly dozen, according to the National UFO Reporting Center. Brooklyn is tops in tin-foil hatters, with 12 close encounters. Not far behind are Manhattan with 11 and Queens with 10. Staten Islanders claim just eight — despite the borough’s rep for not social distancing. The Bronx is even more grounded, chalking up a mere five.

Haim Eshed, 87, former director of space programs for the Israel Ministry of Defense for nearly 30 years said the U.S. and Israel have been in contact with alien life forms representing a “galactic federation,” and President Donald Trump knows about it. Eshed told Israel's Yediot Aharonot newspaper that “humanity is not ready,” for the public disclosure of extraterrestrials who he claims currently are in talks with government agencies on our planet. "There is an agreement between the U.S. government and the aliens. They signed a contract with us to do experiments here," he said. Parts of the interview were...

The joint U.S.-European Solar Orbiter spacecraft had an appointment with Venus this morning (Dec. 27), the first in a series of planetary flybys to hone the probe's orbit on its journey to the sun. Solar Orbiter reached its closest approach to Venus at 7:39 a.m. EST (1239 GMT), when the spacecraft was about 4,700 miles (7,500 kilometers) from the top of the planet's cloud tops. The probe, a partnership between NASA and the European Space Agency (ESA), launched in February, bound to spend seven years studying our sun. But to get as close to our star as scientists want to,...

Like all stars, our Sun is powered by the fusion of hydrogen into heavier elements. Nuclear fusion is not only what makes stars shine, it is also a primary source of the chemical elements that make the world around us. Much of our understanding of stellar fusion comes from theoretical models of atomic nuclei, but for our closest star, we also have another source: neutrinos created in the Sun’s core.Whenever atomic nuclei undergo fusion, they produce not only high energy gamma rays but also neutrinos. While the gamma rays heat the Sun’s interior over thousands of years, neutrinos zip out...

Theory was first postulated in 1930s. Scientists this week announced the landmark detection of elusive particles generated from the fusion of hydrogen in the Sun, confirming a nearly-100-year-old theory about the ways in which many stars generate energy. In a paper published in Nature, a team of researchers called the Borexino Collaboration reported detecting the presence of neutrinos produced during the carbon–nitrogen–oxygen cycle of fusion deep within the Sun. The scientists stated that the energy produced in the CNO cycle represents just a small fraction of the total energy output of our Sun, but “in massive stars, this is the...

Explanation: Big, beautiful spiral galaxy NGC 1055 is a dominant member of a small galaxy group a mere 60 million light-years away toward the aquatically intimidating constellation Cetus. Seen edge-on, the island universe spans over 100,000 light-years, a little larger than our own Milky Way galaxy. The colorful, spiky stars decorating this cosmic portrait of NGC 1055 are in the foreground, well within the Milky Way. But the telltale pinkish star forming regions are scattered through winding dust lanes along the distant galaxy's thin disk. With a smattering of even more distant background galaxies, the deep image also reveals a...

The sun has begun a new 11-year cycle, and scientists have very different ideas on just how much energy will be available to fuel its eruptions. The consensus view of an international panel of 12 scientists calls for the new cycle, Solar Cycle 25, to be small to average, much like its predecessor, Solar Cycle 24. Scott McIntosh, foresees the sun going gangbusters. The cycle is already off to a fast start, coinciding with the recent publication of McIntosh's paper in Solar Physics. The study, with contributions from several of his colleagues, forecasts the nascent sunspot cycle to become one...

As astronomers peering into Earth’s interior, there is no way for them to “feel” the true nature of the core. ... Scientists have long been on this quest, sometimes with fatal consequences. Explorers of old perished trying to set up monitoring stations in far-flung locales, like the doomed English explorer Sir John Franklin, whose expedition to take magnetic observations of the North Pole in 1845 ended with 129 men dead and two ships lost. As soon as long-lasting ground observatories sprung up around the world, scientists noticed strange deviations in the field, including for example, that our magnetic North and...

Explanation: It was time for their close-up. Two days ago Jupiter and Saturn passed a tenth of a degree from each other in what is known a Great Conjunction. Although the two planets pass each other on the sky every 20 years, this was the closest pass in nearly four centuries. Taken early in day of the Great Conjunction, the featured multiple-exposure combination captures not only both giant planets in a single frame, but also Jupiter's four largest moons (left to right) Callisto, Ganymede, Io, and Europa -- and Saturn's largest moon Titan. If you look very closely, the clear...

The Bible tells us very little about the magi. Their story appears but once, in the Gospel of Matthew (2:1-12), where they are described as mysterious visitors "from the east" who come to Jerusalem looking for the child whose star they observed "at its rising." After meeting with King Herod, who feigns an intention to worship the child but actually plans to destroy him, the magi follow the same star to Bethlehem. There, upon seeing the baby Jesus and his mother Mary, the magi kneel down and worship him, presenting him with their three famous gifts -- gold, frankincense and...

Neptune boasts some of the strangest weather in the solar system. The sun’s eighth planet holds the record for the fastest winds observed on any world, with speeds cutting through the atmosphere upward of 1,100 mph, or 1 1/2 times the speed of sound. Scientists still do not know exactly why its atmosphere is so tumultuous. Their latest glimpse of Neptune provided even more reason to be confused. The Hubble Space Telescope identified a storm in 2018, a dark spot some 4,600 miles across. Since that time, it appears to have drifted toward the equator but then swooped back up...

Embrace the flow, says a duo of mechanical engineers at North Carolina State University—the flow of energy, that is. The mantra you might normally hear from your yoga instructor could be an entirely new way of looking at the universe. 🌌The universe is badass. Let's explore it together. The two theorists, Larry Silverberg and Jeffrey Eischen, suggest that fragments of energy, rather than waves or particles, may be the fundamental building blocks of the universe. The bedrock of their theory is the foundational idea that energy is always flowing through space and time. The authors suggest thinking of energy as...

There are three principal reasons why the 4 B.C. date has prevailed over 1 B.C. These reasons were articulated by Emil Schürer in A History of the Jewish People in the Time of Jesus Christ, also published in the 19th century. First, Josephus informs us that Herod died shortly before a Passover (Antiquities 17.9.3, The Jewish War 2.1.3), making a lunar eclipse in March (the time of the 4 B.C. eclipse) much more likely than one in December. Second, Josephus writes that Herod reigned for 37 years from the time of his appointment in 40 B.C. and 34 years from...

FRIDAY, DECEMBER 4 [basically the same as today (Sunday), tomorrow, and next few days] Bright Jupiter and Saturn are closer together now (1.8° apart).Jupiter and Saturn are closing toward their record-breaking conjunction on December 21st, when they will appear only 0.1° apart. That’s about the width of a toothpick at arm’s length!https://skyandtelescope.org/observing/this-weeks-sky-at-a-glance-december-4-12-2/

Explanation: Sixty million light-years away toward the southerly constellation Corvus, these two large galaxies are colliding. The cosmic train wreck captured in stunning detail in this Hubble Space Telescope snapshot takes hundreds of millions of years to play out. Cataloged as NGC 4038 and NGC 4039, the galaxies' individual stars don't often collide though. Their large clouds of molecular gas and dust do, triggering furious episodes of star formation near the center of the wreckage. New star clusters and interstellar matter are jumbled and flung far from the scene of the accident by gravitational forces. This Hubble close-up frame is...

A noontime boom that was heard and felt from southern Ontario to Virginia was likely caused by a disintegrating meteor, according to an organization in western New York that keeps track of such phenomena, the AP reports. Witnesses across the area reported hearing the boom or seeing a fireball in the sky shortly after noon on Wednesday, said Robert Lunsford of the American Meteor Society in Geneseo. By 5pm, the organization had recorded 90 reports of the fireball seen in Maryland, Michigan, New York, Ontario, Pennsylvania, and Virginia. Police agencies and fire departments around central New York received 911 calls...

This aerial view shows the damage to the Arecibo Observatory after its 900-ton equipment platform broke loose, swung into a nearby rock face, and smashed onto the radio dish below. ==================================================================== The Arecibo Observatory’s suspended equipment platform fell hundreds of feet and crashed through the giant radio dish. The Arecibo Observatory’s suspended equipment platform collapsed just before 8 a.m. local time on December 1, falling more than 450 feet and crashing through the telescope’s massive radio dish—a catastrophic ending that scientists and engineers feared was imminent after multiple cables supporting the platform unexpectedly broke in recent months. No one was...

The Arecibo Observatory's platform collapsed this morning due to structural failure. In mid-November, the National Science Foundation had announced that the Observatory would be dismantled because of the danger it posed.
