Buckybomb shows potential power of nanoscale explosives Mar 05, 2015 by Lisa Zyga Enlarge Molecular configuration of an exploding buckybomb. Credit: ACS (Phys.org)—Scientists have simulated the explosion of a modified buckminsterfullerene molecule (C60), better known as a buckyball, and shown that the reaction produces a tremendous increase in temperature and pressure within a fraction of a second. The nanoscale explosive, which the scientists nickname a "buckybomb," belongs to the emerging field of high-energy nanomaterials that could have a variety of military and industrial applications. The researchers, Vitaly V. Chaban, Eudes Eterno Fileti, and Oleg V. Prezhdo at the University of...

Explanation: The faint and somehow menacing cometary globule CG4 reaches through the center of this deep southern skyscape. About 1,300 light-years from Earth toward the constellation Puppis, its head is about 1.5 light-years in diameter and its tail about 8 light-years long. That's far larger than the Solar System's comets that it seems to resemble. In fact, the dusty cloud contains enough material to form several Sun-like stars and likely has ongoing star formation within. How its distinctive form came about is still debated, but its long tail trails away from the Vela Supernova remnant near the center of the...

Explanation: The sprawling Caloris basin on Mercury is one of the solar system's largest impact basins, created during the early history of the solar system by the impact of a large asteroid-sized body. The multi-featured, fractured basin spans about 1,500 kilometers in this enhanced color mosaic based on image data from the Mercury-orbiting MESSENGER spacecraft. Mercury's youngest large impact basin, Caloris was subsequently filled in by lavas that appear orange in the mosaic. Craters made after the flooding have excavated material from beneath the surface lavas. Seen as contrasting blue hues, they likely offer a glimpse of the original basin...

Explanation: What dark structures arise from the Pelican Nebula? Visible as a bird-shaped nebula toward the constellation of a bird (Cygnus, the Swan), the Pelican Nebula is a place dotted with newly formed stars but fouled with dark dust. These smoke-sized dust grains formed in the cool atmospheres of young stars and were dispersed by stellar winds and explosions. Impressive Herbig-Haro jets are seen emitted by a star on the right that is helping to destroy the light year-long dust pillar that contains it. The featured image was scientifically-colored to emphasize light emitted by small amounts of ionized nitrogen, oxygen,...

The Cross in the Cosmos – A Meditation on a Teaching by Joseph Cardinal Ratzinger By: Msgr. Charles PopeThe Wisdom Tradition of the Scriptures emphasizes that God speaks and is discerned in things He has made. Scripture says, The heavens declare the glory of God, the firmament (stars) shows forth his handiwork (Psalm 19:1). Indeed, when God spoke His Word, creation came forth.And the Word that God spoke was the Logos, Jesus. Scripture says, Through him all things were made; without him nothing was made that has been made (Jn 1:3). It also says, For by Him all things were created, both in...

Explanation: It was late in the northern martian spring when the HiRISE camera onboard the Mars Reconnaissance Orbiter spied this local denizen. Tracking across the flat, dust-covered Amazonis Planitia in 2012, the core of this whirling dust devil is about 140 meters in diameter. Lofting dust into the thin martian atmosphere, its plume reaches about 20 kilometers above the surface. Common to this region of Mars, dust devils occur as the surface is heated by the Sun, generating warm, rising air currents that begin to rotate. Tangential wind speeds of up to 110 kilometers per hour are reported for dust...

A object from the very early universe is bafflingly rich with dust that theory says shouldn't have formed yet. Photograph by NASA, ESA, the Hubble Heritage Team (STScI/AURA), J. Blakeslee (NRC Herzberg Astrophysics Program, Dominion Astrophysical Observatory), and H. Ford (JHU) Astronomers have spotted a surprisingly dusty little galaxy within the cluster Abell 1689, shown here in an image by the Hubble telescope. Peering back in time to find the very earliest objects in the universe, an international team of astronomers has discovered a galaxy that shouldn't be there at all. The problem, the scientists report Monday in Nature, is...

Order! Order in the Universe! – A Meditation on the Wisdom That Creation Reflects By: Msgr. Charles PopeIn a courtroom, the judge can bring an unruly outburst to an end by shouting, “Order! Order in the court!” I often feel the same urge in the debates of our time about God’s existence and His role in the created universe. It is not so much that the debates can get unruly, but that I, with the  insistence of a town crier, want to shout, “Order! Order, there IS order the universe!” And I want to ask everyone to be quiet and listen to the universe herself...

Explanation: It is not every day that such an interesting cloud photobombs your image. The original plan was to photograph a rare angular conjunction of Mars and Venus that occurred a week and a half ago, with the added bonus of a crescent Moon and the International Space Station (ISS) both passing nearby. Unfortunately, on Madeira Island, Portugal, this event was clouded out. During the next day, however, a spectacular lenticular cloud appeared before sunset, so the industrious astrophotographer quickly formulated a new plan. A close look at the resulting image reveals the Moon visible toward the left of the...

Somewhere along the line of modern history, the idea has taken root, spread, and become commonly held among seculars that religious people hold to a Faith that is separate from, and at odds with, natural reason. Modern science, following the lead of modern philosophy and modern secularized religion, has fallen for the heretical notion that there are two separate tracks of history: a material track, which many assume to be the true one and to which many attach all their trust, and the spiritual one, which is reduced by many to mere fantasy; a delusion held by believers to bring...

Explanation: Almost every object in the above photograph is a galaxy. The Coma Cluster of Galaxies pictured above is one of the densest clusters known - it contains thousands of galaxies. Each of these galaxies houses billions of stars - just as our own Milky Way Galaxy does. Although nearby when compared to most other clusters, light from the Coma Cluster still takes hundreds of millions of years to reach us. In fact, the Coma Cluster is so big it takes light millions of years just to go from one side to the other! The above mosaic of images of...

Trigonometry Is Racist! KEVIN D. WILLIAMSON February 27, 2015 An African-American scholar says that emphasis on STEM education is bad for blacks. Earlier today on Sirius XM Urban View, an African-American talk station, the guest was Daryl Scott, president of the Association for the Study of African American Life and History. The conversation turned to STEM — science, technology, engineering, and math — education, and the origins of the ongoing push to encourage institutions and students to focus on those subjects. Can you guess what happened? In 1983, the guest explained, a commission empaneled by the secretary of education issued...

ISIL and other Islamist jihad movements continue to round up and silence all who oppose them or refuse to convert to their extreme religious tenets. They are inspiring thousands to join them. Their intolerance, vicious tactics and growing power seem to have inspired others, as well.After years of claiming the science is settled and unprecedented manmade catastrophes are occurring right now, Climate Crisis, Inc. has gotten desperate. Repeated polls put climate change at the bottom of every list of public concerns. China and India refuse to cut energy production or emissions. Real-world weather and climate totally contradict their dire models...

When a researcher gets proved wrong, that means the scientific method is working. Scientists make progress by re-doing each other’s experiments—replicating them to see if they can get the same result. More often than not, they can’t. “Failure to reproduce is a good thing,” says Ivan Oransky, co-founder of Retraction Watch. “It happens a lot more than we know about.” That could be because the research was outright fraudulent, like Wakefield’s. But there are plenty of other ways to get a bum result—as the Public Libary of Science’s new collection of negative results, launched this week, will highlight in excruciating...

Explanation: Taken on February 20, five different exposures made in rapid succession were used to created this tantalizing telephoto image. In combination, they reveal a wide range of brightness visible to the eye on that frigid evening, from the urban glow of the Quebec City skyline to the triple conjunction of Moon, Venus and Mars. Shortly after sunset the young Moon shows off its bright crescent next to brilliant Venus. Fainter Mars is near the top of the frame. Though details in the Moon's sunlit crescent are washed out, features on the dark, shadowed part of the lunar disk are...

Explanation: Buffeted by the solar wind, Comet Lovejoy's crooked ion tail stretches over 3 degrees across this telescopic field of view, recorded on February 20. The starry background includes awesome bluish star Phi Persei below, and pretty planetary nebula M76 just above Lovejoy's long tail. Also known as the Little Dumbbell Nebula, after its brighter cousin M27 the Dumbbell Nebula, M76 is only a Full Moon's width away from the comet's greenish coma. Still shining in northern hemisphere skies, this Comet Lovejoy (C/2014 Q2) is outbound from the inner solar system some 10 light-minutes or 190 million kilometers from Earth....

Roger Pielke, a professor of environmental studies at the University of Colorado, and six others are under investigation by Congress regarding testimony they've given on the subject of climate change.Pielke, a believer in man-caused global warming, can't quite figure out why he's the object of a witch hunt....................... What am I accused of that prompts being investigated? Here is my crime: Prof. Roger Pielke, Jr., at CU’s Center for Science and Technology Policy Research has testified numerous times before the U.S. Congress on climate change and its economic impacts. His 2013 Senate testimony featured the claim, often repeated, that it...

Explanation: Venus, named for the Roman goddess of love, and Mars, the war god's namesake, came together by moonlight in this lovely skyview, recorded on February 20 from Charleston, South Carolina, USA, planet Earth. Made in twilight with a digital camera, the three second time exposure also records earthshine illuminating the otherwise dark surface of the young crescent Moon. Of course, the Moon has moved on from this much anticipated triple conjunction. Venus still shines in the west though as the evening star, third brightest object in Earth's sky, after the Sun and the Moon itself. Seen here within almost...

Explanation: The Rosette Nebula is not the only cosmic cloud of gas and dust to evoke the imagery of flowers -- but it is the most famous. At the edge of a large molecular cloud in Monoceros, some 5,000 light years away, the petals of this rose are actually a stellar nursery whose lovely, symmetric shape is sculpted by the winds and radiation from its central cluster of hot young stars. The stars in the energetic cluster, cataloged as NGC 2244, are only a few million years old, while the central cavity in the Rosette Nebula, cataloged as NGC 2237,...
