Spettacolo!

This is the best time to spot a rare alignment of five planets. Here's how to watch it. | Live Science

The early bird catches the spectacular skywatching this week, as five planets march across the predawn sky.
This rare planetary alignment has been visible since early June. But the view should be particularly impressive this week, as Mercury is at its brightest and the waning moon joins the parade of planets.

:D :clap:

A hundred million years ago...

Life Helps Make Almost Half of All Minerals on Earth

A new origins-based system for classifying minerals reveals the huge geochemical imprint that life has left on Earth. It could help us identify other worlds with life too.


:D :clap:

A hundred million years ago, a sea creature called an ammonite died and its hard carbonate shell settled into the seabed as a biomineral, aragonite. Over time, the carbonate was gradually replaced with silicate crystals of opal.

Bella domanda

Where is Attila the Hun's tomb? | Live Science

Attila the Hun, who invaded and ravaged both the western and eastern halves of the Roman Empire during the fifth century A.D., died on his wedding night at age 58. It's a matter of debate whether Attila died of natural causes, or whether his new wife, Ildico, murdered him. But despite his murky ending, does anyone know where he was buried?

In a word, no. The tomb of Attila the Hun (A.D. 395-453) has never been found and it is unclear where exactly it is.

:eek: :D :clap:

Magic moment: brava!!

Large Hadron Collider Finds Evidence of 3 Never-Before-Seen Particles

Physicists say they've found evidence in data from Europe's Large Hadron Collider for three never-before-seen combinations of quarks, just as the world's largest particle-smasher is beginning a new round of high-energy experiments.

"It's a magic moment now," CERN Director-General Fabiola Gianotti said during today's webcast. "We just had collisions at an unprecedented energy, 13.6 tera-electronvolts, and this opens a new era of exploration at CERN."


:clap: :clap: :clap:

Sempre in topic!

Mysterious 'Lord of The Universe' Mentioned in Ancient Palmyra Has Just Been Identified

The identity of an unknown god described in inscriptions from the ancient city of Palmyra, located in modern-day Syria, has long baffled scientists. But now, a researcher declares that she has cracked the case.

Palmyra existed for millennia and the city flourished around 2,000 years ago as a center of trade that connected the Roman Empire with trade routes in Asia, such as the Silk Road.

The anonymous deity is mentioned in numerous Aramaic inscriptions at Palmyra and is referred to as "he whose name is blessed forever," "lord of the universe" and "merciful."

Un ammasso di galassie: ecco la prima immagine dai confini dell’Universo

L’Universo si spinge un po' più in là. O, meglio, gli occhi tecnologici dell’umano hanno permesso di ottenere «l'immagine più profonda dell'Universo mai catturata». Le foto erano pronte per essere diffuse martedì alle 16,30 ora italiana, ma il presidente Joe Biden insieme alla vice Kamala Harris e al numero uno della Nasa Bill Nelson hanno voluto anticipare alla vigilia, celebrando il momento storico per la scienza, per «l’America e per l’intera umanità».

Exceptional treasure

Ancient hoard of gold Roman coins discovered in plowed UK field

Experts believe that the "exceptional" treasure trove could lead to more discoveries in the area

A cache of gold coins found buried on farmland in the United Kingdom has caught the attention of coin experts, who have linked the treasure trove to the Roman Empire.
So far, metal detectorists have discovered 11 coins on a remote stretch of cultivated field located in Norfolk, a rural county near England's eastern coast, and experts remain hopeful that more could be unearthed in the future.

:D :clap:

Amazing resolution: ma dai...

This Stunning Image Shows a Star Like You Have Never Seen One Before

It looks a bit like neon artwork from the '80s. But what the image really shows is much, much cooler.

It's a star, and the first light image captured by the newest instrument on the Gemini South telescope, the Gemini High-resolution Optical SpecTrograph, or GHOST. What it shows is the entire optical spectrum of light emitted by a star named HD 222925, in amazing resolution.

Un bel terno sulla Ruota del Carro!!

La galassia Ruota di carro svelata dal telescopio Webb

Nata da una collisione, sta lentamente cambiando struttura

Il telescopio spaziale James Webb svela dettagli mai visti prima della lenta trasformazione in atto nella galassia Ruota di carro, chiamata così per il suo particolare aspetto.

Situata a 500 milioni di anni luce nella costellazione dello Scultore, è nata dalla collisione tra una grande galassia a spirale e un'altra galassia più piccola: lo scontro ha generato due anelli che si espandono verso l'esterno come le increspature create da un sasso nello stagno. Grazie al nuovo telescopio di Nasa, Agenzia spaziale europea (Esa) e canadese (Csa), è stato possibile individuare con estrema precisione singole stelle e regioni di formazione stellare, oltre che svelare il comportamento del buco nero al centro della galassia.

Ruota di carro ha un nucleo contenente un'enorme quantità di polvere calda, con le aree più luminose che ospitano giganteschi giovani ammassi stellari.

Spettacolo gravitazionale!!

Look at What Happens When Two Galaxies Collide

Gravity can do some pretty astonishing things out there in the universe. When it’s not ensuring the downward trajectory of your spilled coffee directly onto your shirt here on Earth, the invisible force is playing arts and crafts with cosmic matter: crushing gas and dust into radiant new stars, smoothing clumpy rock into spherical planets, and, my personal favorite, smushing entire galaxies together.

:D :clap:

Grande Giove che meraviglia!!

Tempeste, aurore e anelli: dal Webb telescope immagini di Giove senza precedenti

“È veramente notevole come si possano vedere tanti dettagli di Giove nella stessa immagine: gli anelli, piccoli satelliti e persino delle galassie”, ha commentato l'astronoma planetaria Imke de Pater, professoressa emerita dell'Università della California, che ha svolto un ruolo chiave nel progetto.

"Non abbiamo mai visto Giove in questo modo. È tutto abbastanza incredibile", ha detto de Pater, "Non ci aspettavamo davvero che fosse così bello, ad essere onesti", ha aggiunto.

Love hurts

‘Clinically awful’: why the pain of a broken heart is real

Poets and songwriters have long known that love hurts, but now scientists are examining the physical anguish caused by a breakup – and the results are helping people understand and recover from their distress

The Universe, truly, is full of wonders

Extraordinary Phenomenon in Space Captured by Spellbinding New Image

The Universe, truly, is full of wonders, and the James Webb Space Telescope has just given us our best views of one of them yet.

The object in question is a star around 5,600 light-years away, and Webb's infrared eye has picked out an extraordinary detail: it's surrounded by what appear to be concentric rings of light radiating outward.
While Webb's characteristic diffraction spikes are not 'real', those concentric rings are – and there's a wonderful and fascinating explanation for them.

Ah, the sounds of late summer...

The Spookiest Sound in Astronomy

Ah, the sounds of late summer. Pass a pool, and hear the happy yelps of kids splashing around. Sit outside at night, and bask in the soothing buzz of cicadas hidden in the trees. Open the internet, and hear the terrifying howling of outer space.

Thank NASA for that last one. The space agency recently shared a clip online of sound coming from a cluster of galaxies about 250 million light-years from Earth. NASA, always eager to show off its capacity to produce cosmic wonder, presented the audio enthusiastically, as if to say, Wow, check out this cool thing! And although the transformation of space phenomena into something detectable by our human ears certainly seems like an exciting exercise, the reality is—well, have a listen.

The noise sounds like a ghostly wail, or the horror-movie music just before a jump scare, or, as several people have pointed out, the cries of countless souls trapped in eternal darkness. Just nothing good; less awe-ful, and more awful. Does space really sound this scary?
