Cosmic Buckyballs Could Be Mysterious Infrared Light Source

Scientists may have just traced the source of some of the mysterious infrared emission detected from stars and clouds of interstellar dust and gas. This Unknown Infrared Emission Band (UIE) has baffled scientists for decades; According to a new theoretical work, at least some of these bands could be produced by highly ionized buckminsterfullerene, better known as buckyballs. “I am very honored to have played a part in the extremely complex quantum chemical investigations carried out by Dr Sadjadi that have produced these very exciting results,” said astrophysicist Quentin Parker of the Space Research Laboratory of the University of Hong Kong. “First they looked at the theoretical evidence that Fullerenes – Carbon 60 – can withstand very high ionization rates, and now this work shows the infrared emission signature of the species is a perfect match for some of the most prominent Unknown Infrared Emission features known. This will help re-strengthen this area of ​​research.” Buckminste

Astronomers describe the star birth web of the cosmic Tarantula Nebula

This composite image of the star-forming region of Doradus 30 — also known as the Tarantula Nebula — reveals areas of cold gas that could collapse to form stars. (Image credit: ESO, ALMA (ESO/NAOJ/NRAO)/Wong et al., ESO/M.-R. Cioni/VISTA Magellanic Cloud survey.) The newly released image of 30 Doradus, also known as the Tarantula Nebula, reveals thin, spiderweb-like strands of gas that reveal a dramatic battle between gravity and stellar energy that could give astronomers an idea of ​​how massive stars have shaped this star formation. regions and why they continue to be born in these molecular clouds. This high-resolution image of the Tarantula Nebula, located 170,000 light-years from Earth, consists of data collected by the Atacama Large Millimeter/submillimeter Array (ALMA). Located in the Large Magellanic Cloud, a satellite galaxy of the Milky Way, the Tarantula Nebula is one of the brightest star-forming regions in our galaxy’s backyard. It’s also one of the most active in term

Nichelle Nichols, groundbreaking Star Trek actress, dies aged 89

Despite the concerns, the episode aired without blowback. In fact, it got “the most fan mail Paramount has ever gotten on Star Trek for a single episode,” Nichols said in a 2010 interview with Archive of American Television. “I would say more about the pioneer, the unrivaled Nichelle Nichols, who shared the bridge with us as Lt. Uhura from USS Enterprise, and who graduated today at the age of 89,” George Takei wrote on Twitter. “For today, my heart is heavy, my eyes shine like the stars you are in now, my dear friend.” Takei plays Sulu in the original Star Trek series with Nicols. But its impact is felt beyond its direct co-stars, and many others in Star Trek the world also tweeted their condolences. Celia Rose Gooding, who is currently playing Uhura in Star Trek: A Strange New World , wrote on Twitter that Nichols “made room for so many of us. He is a reminder that not only can we reach the stars, but our influence is vital to their survival. Forget about shaking the table, he

Alexandra George, fiancé to Nick ‘Honey Badger’ Cummins, held a baby shower on Sunday, ahead of welcoming the couple’s first child. The jewelery designer shared a series of pictures to Instagram, detailing the celebration with family and friends. ‘Beautiful baby shower for our little one. It is very fortunate to mention the family of this beautiful woman. Feeling love,’ she wrote in one caption. Alexandra George (pictured), fiancé of Nick ‘Honey Badger’ Cummins, held a baby shower on Sunday, ahead of welcoming the couple’s first child Alexandra added: ‘Ps. Any parenting suggestions are welcome’. He wrote in the second caption: ‘My sister from another master. Can’t imagine living away from my family without the support of the Cummins girls! Love you all’. In the picture, Alexandra holds her baby bump as she poses in a stunning floral maxi dress.

This Record-Breaking 'Black Widow' Pulsar Is The Biggest Neutron Star Ever

One of the most extreme stars in the Milky Way has just gotten even weirder. Scientists have measured the mass of a neutron star named PSR J0952-0607, and found that it is the most massive neutron star ever discovered, registering 2.35 times the mass of the Sun. If true, this is very close to the theorized upper mass limit of about 2.3 solar masses for neutron stars, which is an excellent laboratory for studying these ultra-dense stars at what we think are on the verge of collapse, in hopes of better understanding. strange quantum states of the matter they are made of. “We know roughly how matter behaves at nuclear densities, such as in the nuclei of uranium atoms,” said astrophysicist Alex Filippenko of the University of California, Berkeley. “A neutron star is like one giant core, but when you have one and a half solar masses of this material, which is about 500,000 Earth masses of cores all stuck together, it’s not at all clear how they’re going to behave.” Neutron stars are the col

The astrophotography competition presents spectacular heavenly images

With his love of science fiction and photography, it seems that Ian Inverarity has always been destined to become involved with astrophotography. Key points: A mechanical engineer from Adelaide has won this year’s David Malin astrophotography award Amateur astrophotography is booming as a hobby as technology becomes more advanced and affordable This year’s competition entered the smartphone category for the first time Mechanical engineers have been capturing the wonders of the night sky for several years now, traveling to regional South Australia in search of the perfect shot. He said the addictive pursuit took him to Gawler, north of Adelaide, about once a month. And many nights and hours in darkness have paid off, with his photo of an old gum tree at Gawler shrouded in mist before the Milky Way picks up this year’s David Malin astrophotography award in New South Wales. “It’s relatively unusual. Out of the seven years or so I’ve been going there, I’ve only encountered fog at night,” I
