The legendary Peruvian Huaca is a 30-metre-high (98.42 ft) rock face painted with mythological scenes including an ancient deity surrounded by indigenous warriors. An article in La República reports that the site was first rediscovered in 1916 by a group of huagueros, or treasure hunters , in Illimo, near the city of Chiclayo, the capital city of northwest Peru’s Lambayeque region.

The beautiful chaos of two merging galaxies shines in the latest image captured by the James Webb Space Telescope.
Vice President Kamala Harris and French President Emmanuel Macron viewed the new Webb image, along with a new composite of the Pillars of Creation captured by the space observatory, during a visit to NASA Headquarters in Washington on Wednesday.
The Webb telescope, designed to observe faint, distant galaxies and other worlds, is an international mission between NASA and its partners, the European Space Agency and Canadian Space Agency.

Albert Einstein’s Theory of Relativity, which was published in 1905, suggested that gravitational waves, which are oscillations of the space-time fabric, exist. Now, more than a century later, we have proof that they do. Now, a new study has found clear signs of relativistic precession in the paths of two black holes that are crashing into each other.
Since gravitational waves were first found in 2015, this area has become a good place for modern astrophysics, letting experts see things they couldn’t see before.
The coming together of two black holes is without a doubt one of the biggest and most violent things that can happen. As the two bodies move toward their inevitable end, they do a dance that looks like the end of the world. This dance and the fusion itself use so much energy that the fabric of space-time shakes like a sheet.

Α cosmic ray detectioп experimeпt has discovered particles that may be from a parallel υпiverse that also emerged from the Big Baпg, accordiпg to the Daily Star.

The James Webb Space Telescope has captured a unique perspective of the universe, including never-before-seen galaxies that glitter like diamonds in the cosmos.
The new image, shared on Wednesday as part of a study published in the Astronomical Journal, was taken as part of the Prime Extragalactic Areas for Reionization and Lensing Science observing program, called PEARLS.
It’s one of the first medium-deep-wide-field images of the universe, with “medium-deep” meaning the faintest objects visible, and “wide-field” referring to the region of the cosmos captured in the image.

A fresh set of 168 geoglyphs have been discovered by researchers in Peru’s intriguing Nazca Lines UNESCO World Heritage Site. The newly found drawings depict humans, camelids, birds, orcas, cats and snakes as well as simple lines and geometrical patterns.
Interestingly, one of the 50 or so human figures in the set is cartoon-like, with big rounded eyes and a stubble-like patch around the mouth, and bears a resemblance to Homer Simpson, the popular American animated sitcom character, reports the Daily Mail !
According to Science Alert , when the Nazca Lines , located in the Nazca Desert some 400 kilometers (249 miles) south of Lima, was designated a World Heritage Site in 1994, only around 30 geoglyphs had been identified and they mostly depicted plants and animals. By 2019 the number had risen to around 200 geoglyphs, several of which were human-like figures. However, Peruvian archaeologist Luis Jaime Castillo told The Guardian in 2020, he believed this to be only 5 percent of the total number out there.
No one has yet managed to travel through time – at least to our knowledge – but the question of whether or not such a feat would be theoretically possible continues to fascinate scientists.
As movies such as The Terminator, Donnie Darko, Back to the Future and many others show, moving around in time creates a lot of problems for the fundamental rules of the Universe: if you go back in time and stop your parents from meeting, for instance, how can you possibly exist in order to go back in time in the first place?
It’s a monumental head-scratcher known as the ‘grandfather paradox’, but in September last year a physics student Germain Tobar, from the University of Queensland in Australia, said he has worked out how to “square the numbers” to make time travel viable without the paradoxes.
An incredibly bright flash that appeared in the night sky in February was the result of a star straying too close to a supermassive black hole, meeting its untimely end there as it was ripped to shreds.
But the rare cosmic event actually occurred 8.5 billion light years away from Earth, when the universe was just a third of its current age — and it has created more questions than answers.
The signal from the luminous explosion, known as AT 2022cmc, was first picked up by the Zwicky Transient Facility at the California Institute of Technology’s Palomar Observatory on February 11.

Sean Carroll is a physicist at Caltech. His research includes theoretical physics and astrophysics, especially cosmology, field theory, and gravitation. He has published several research papers dark matter and dark energy, modified gravity, violations of Lorentz invariance, extra dimensions, topological defects, cosmic microwave background anisotropies, causality violation, black holes, and the cosmological constant problem.
He is currently focused on the origin of the universe and the arrow of time, including the roles of inflation, baby universes, and quantum gravity. In his recent video by Techinsider, he explains what existed before Big Bang and what it actually means.
Astronomers have been discovering an increasing number of rocky exoplanets, worlds similar in size to Earth. This month (December 15, 2022), an international team of astronomers said it has found two more worlds in our own neighborhood of the galaxy. These worlds are less than 16 light-years away, very close, relatively speaking! And they’re in the habitable zone of their star, the zone within which liquid water can exist.
For comparison, Proxima Centauri b is the closest Earth-mass exoplanet, at 4.2 light-years away. It’s also similar in size to Earth and in its star’s habitable zone.
