The upshot of this current solar minimum (24) –the sun’s deepest of the past 100+ years (NASA)– is a cooling of the planet, with the coming solar cycle (25) forecast by NASA to be “the weakest of the past 200 years“

If there is life in the Solar System outside of Earth, Jupiter's moon Europa and Saturn's moon Enceladus are two of the most likely spots to hold them. However, any extraterrestrial creatures on these celestial objects probably are not related to us, according to a new study. The research, presented at the annual fall meeting of the American Geophysical Union by Purdue University geophysicist Jay Melosh, looked at the idea of "lithopanspermia," an idea that life hopped from one planet to another via rocks that were ejected into space, according to Space.com, which first reported the news.

In the first of these new images, taken on Nov. 16, the comet was approximately 203 million miles from Earth, seen in front of a distant spiral galaxy known as 2MASX J10500165-0152029, according to a NASA statement. You can see the comet's tail of dust up to the right. You can also see that the object's bright core looks smudged, as Hubble was imaging the object while also tracking its movement. In both images, 2I/Borisov has been artificially colored blue so that details can be seen in the coma, or envelope of dust and material that surrounds the comet's core,...

"Alcohol is basically pure calories, pure energy, non-nutritive and super toxic at high doses," study co-author Stephen Ilardi, PhD, an associate professor of clinical psychology at the University of Kansas, said in a statement. "Sugars are very similar. We're learning when it comes to depression, people who optimize their diet should provide all the nutrients the brain needs and mostly avoid these potential toxins." This is especially true for those who are prone to seasonal depression, which affects approximately half a million Americans. As with drinking several glasses of wine, eating a box of cookies might provide a temporary feeling...

Daily observations of the number of sunspots since 1 January 1900 according to Solar Influences Data Analysis Center (SIDC). The thin blue line indicates the daily sunspot number, while the dark blue line indicates the running annual average. The recent low sunspot activity is clearly reflected in the recent low values for the total solar irradiance. Data source: WDC-SILSO, Royal Observatory of Belgium, Brussels.

Professor Valentina Zharkova’s recent paper ‘Oscillations of the Baseline of Solar Magnetic Field and Solar Irradiance on a Millennial Timescale’ has been accepted for publishing in Nature. It confirms a Grand Solar Minimum (GSM) from 2020 to 2055, as all four magnetic fields of the sun go out of phase, while also suggesting centuries of natural warming post-Minima. Zharkova’s team’s expanded ‘double dynamo’ calculations match-up almost perfectly with the timelines of past Grand Minimas: the Maunder Minimum (1645–1715), Wolf minimum (1300–1350), Oort minimum (1000–1050), Homer minimum (800–900 BC); as well as with the past Grand Maximas: the Medieval Warm Period...

Mysterious lights hovering above the east Valley have many wondering if we've had a close encounter. The couple says they spotted the phenomenon outside their Mesa home on Sunday around nine that night. They say the object seemed to come from the southeast. The object captured on two cell phones looks like a bright orb hovering silently in the sky. Every few moments, the object appears to drop what looks to be flares towards the ground. ABC15 reached out to several aviation experts who theorized the lights seen Sunday could be from parachute flares used by the military or even...

A mathematician at Carnegie Mellon University has developed an easier way to solve quadratic equations. The mathematician hopes this method will help students avoid memorizing obtuse formulas. His secret is in generalizing two roots together instead of keeping them as separate values. ========================================================================== A mathematician has derived an easier way to solve quadratic equation problems, according to MIT's Technology Review. Quadratic equations are polynomials that include an x², and teachers use them to teach students to find two solutions at once. The new process, developed by Dr. Po-Shen Loh at Carnegie Mellon University, goes around traditional methods like completing...

It's one of the brightest annual displays. Stargazers are in for a treat this December as one of the brightest annual displays is expected to light up the sky. The Geminid meteor shower can be seen between the 4th and the 17th of December, peaking on Saturday 14th when around 120 meteors will be expected to be visible per hour. Thanks to the brightness of the individual meteors, it's considered to be one of the best to observe. "In December every year, the Earth crosses the orbital path of the Apollo asteroid 3200 Phaethon. As the asteroid’s orbit takes it...

The Abell 85 galaxy cluster, which is home to a black hole of 40 billion solar masses Mathias Kluge/USM/MPE ===================================================================== Astronomers from the Max Planck Institute for Extraterrestrial Physics and at the University Observatory Munich have found the largest known black hole in our galactic neighborhood using direct mass measurements. Located 700 million light-years from Earth in the Abell 85 cluster of galaxies in the constellation of Cetus, it has a mass 40 billion times that of the Sun. Ever since the existence of the first black hole was confirmed in 1971, they have gone from being a mathematical curiosity...

Astronomers have captured the best and closest image to date of interstellar comet 2I/Borisov, a visitor that originated from outside of our solar system and is currently passing through. On Sunday, the comet will pass within 190 million miles of Earth on its closest approach before continuing on through our solar system. As it gets closer to Earth, the icy comet is shedding more gas and dust through its tail through evaporation. Astronomers at Yale University used the W.M. Keck Observatory's Low-Resolution Imaging Spectrometer, located in Hawaii, to provide the closest look at the interstellar comet since it was first...

The space rock will fly harmlessly past our planet. Asteroid VH5 2019 will make its flyby at about 17.9 lunar distances on Dec. 8, according to the Center for Near-Earth Object Studies at NASA’s Jet Propulsion Laboratory. The asteroid has dimensions of 57 meters (187 feet) by 130 meters (426.5 feet), NASA says. Citing the asteroid’s dimensions, the Inquisitr website describes the rock as “pyramid-shaped,” noting that it is almost as large as the famous Great Pyramid of Giza. The Apollo asteroid is one of five space rocks set to fly by Earth over the weekend, according to the Inquisitr,...

COLORADO SPRINGS — Biology textbooks used in American high schools do not go near the sensitive question of whether genetics can explain why African-Americans are overrepresented as football players and why a disproportionate number of American scientists are white or Asian. But in a study starting this month, a group of biology teachers from across the country will address it head-on. They are testing the idea that the science classroom may be the best place to provide a buffer against the unfounded genetic rationales for human difference that often become the basis for racial intolerance. At a recent training in...

Astronomers have discovered more than 20,000 so-called near-Earth asteroids, or space rocks whose orbits pass within about 30 million miles (50 million kilometers) of Earth's orbit. Whereas comets erupt with long tails of gas, dust and debris when they streak near the sun, the vast majority of near-Earth asteroids appear inert. However, previous research found that a small number of asteroids, such as the asteroid 133P/Elst-Pizarro, could actively erupt with large amounts of dust and bits of rock — enough to create temporary clouds or comet-like tails that are visible from Earth-based telescopes. Much remains unknown about what drives such...

For a little NASA spacecraft, the weather outside is frightful. The Parker Solar Probe is on a mission toward the sun. The spacecraft has been exposed to scorching temperatures and intense sunlight as it draws closer with every loop around. Eventually, Parker will glide through the star’s outer atmosphere and feel the toastiness of nearly 2 million degrees Fahrenheit (more than 1 million degrees Celsius). Parker is dressed appropriately for the journey. It wears a thick, custom-made shield to protect its scientific instruments and systems, and tubes with flowing water to cool itself down. Inside, it is a cozy 78...

Details regarding the incoming space rock have been collected by NASA’s Center for Near-Earth Object Studies (CNEOS). The agency noted that the asteroid, which has been identified as 2019 WW, is currently flying across space towards Earth at an average speed of almost 22,000 miles per hour. According to CNEOS, the asteroid has an estimated diameter of 236 feet, making it longer than the wingspan of a Boeing 747 plane. 2019 WW has been labeled as an Apollo asteroid due to its natural orbit. Like other Apollo asteroids, 2019 WW follows a wide orbit around the Sun and the Earth....

Outbursts of energetic particles that hurtle out from the sun and can disrupt space communications may be even more varied and numerous than previously thought, according to results from the closest-ever flyby of the sun. The finding that these energetic particle events are more varied and numerous than previously known was one of several discoveries made by the instrument suite known as the Integrated Science Investigation of the Sun (ISOIS), a project led by Princeton University that involves multiple institutions as well as NASA. ISOIS seeks to find out how the particles become so fast moving, and what is pushing...

Some biologists might shudder at the thought of eliminating Darwinism from their scientific work. A “Darwin-ectomy” sounds more painful than a tonsillectomy or appendectomy. To hard-core evolutionists, it might sound like a cephalectomy (removal of the head)! If Darwinism is as essential to biology as Richard Dawkins or Jerry Coyne argues, then removing evolutionary words and concepts should make research incomprehensible. If, on the other hand, Darwinism is more of a “narrative gloss” applied to the conclusions after the scientific work is done, as the late Philip Skell observed, then biology would survive the operation just fine. It might even...

Humans have good reason to fear comets, asteroids and other massive space objects. Now we’d like to add ‘mini-moons’ to the list of heavenly bodies we should be worried about. Scientists have claimed our planet was recently hit by one of these mysterious rocks, which exploded in a gigantic fireball. A mini-moon is an object which becomes entangled in Earth’s orbit as it’s zooming through space. It will either whirl around the planet harmlessly forever, zoom off back off on its journey through the solar system or, in the worst case, smash into our planet. ‘Objects gravitationally captured by the...
