Are aliens secretly observing us from Earth’s shadow? A new scientific theory suggests that extraterrestrial probes could be hiding in positions where they remain undetected by our telescopes.

Earth’s Hidden Secrets: Scientists Suggest Alien Probes May Be Hiding Behind Earth

The floating "magic islands" of Titan, Saturn's largest moon, have long intrigued scientists. But a new study now seems to clear the air over these islands and what constitutes them.

The floating "magic islands" of Titan, Saturn's largest moon, have long intrigued scientists. But a new study now seems to clear the air over these islands and what constitutes them. Shaped like a honeycomb, and sometimes even resembling Swiss cheese, these islands on Titan are simply glacier-like snow clusters. The latest revelations about Saturn's moon Titan were made in a study published in Geophysical Research Letters journal. The Cassini-Huygens spacecraft was the first to observe these so-called islands. The Saturnian moon is filled with liquid methane and ethane lakes and these islands looked like shiny, moving spots above these lakes. However, they weren't always visible and vanished from time to time. Xinting Yu, an assistant professor at the Department of Physics and Astronomy at the Univerisity of Texas, led new research on Titan's magical islands, which suggests that they are "floating chunks of porous, frozen organic solids in shapes similar to honeycomb or Swiss cheese." They likely stash after it snows from the sky of Titan, a moon larger than Mercury.

The thick, upper atmosphere clumps together, freezes, and snows onto the surface and into the lakes of methane and ethane due to the presence of organic molecules. As the liquid bodies on Titan's surface are already packed with organic molecules, the complex organic "snow" molecules do not dissolve as soon as they hit them. "For us to see the magic islands, they can't just float for a second and then sink. They have to float for some time, but not for forever, either," Yu said. The hollow holes and tubes in the snow clumps would allow them to float if they were large enough or porous until methane or ethane oozed inside, causing them to sink after filling the voids. However, according to the model by Yu and her colleagues, the snow clumps would be too small to let this mechanism happen. But enough of this snow clustered on the lakeside shores, large pieces could break off and float on the lakes of methane and ethane, similar to how ice sheets break from glaciers and float on the surface of the seas on Earth. This mechanism is known as calving. Yu and her team have also explained another enigma on Saturn's Titan about the peaceful liquid bodies with waves no bigger than a few millimetres. According to the study, a floating blanket of frozen solids covers the surface of liquid bodies on Titan, granting them smoothness. (With inputs from agencies)

While team mapping radio waves in the universe, astronomers have come across a mysterious object that is releasing giant bursts of energy three times an hour, as per a study published on Wednesday (January 26) in the journal <a href="https://www.nature.com/articles/s41586-021-04272-x.epdf?sharing_token=g0qDpzHgeaSaA6mUmwx649RgN0jAjWel9jnR3ZoTv0Of-uh9vqemKMq6w79pifdqdaY5xxIT2ZG7_2UyUWitYHtn2nWAH0KN9KVH1ZPtBPDePVfuAa1sz-qkpQHRO8lx4QaBnNSzyWapSmBR_chuTr1cSMqeS7wZGcpJ86k4qrPi673QqygyKuCUQdEXkI5ouo3YZQhKAoAFYVlm3I-I4ac24yAbE3svoj_w8xA8-_5zWSQOVishTx_VUR2a3fp-8dQY3APRD7IW2SmarKahJk-fpdNXg_aMYoCtzMP2RoiUhT6-w-n_GGFP57eM0LKh&amp;tracking_referrer=edition.cnn.com">Nature</a>.

It is being termed as unlike anything astronomers have seen before but the team that discovered the celestial object believe it could be a neutron star or a white dwarf with an ultra-powerful magnetic field.&nbsp;

As per the astronomers, the strange object, which appeared to be spinning around in space, sends out a beam of radiation that crosses our line of sight, and for a minute in every twenty. The published study claimed it to be one of the brightest radio sources in the sky.

Astrophysicist Dr Natasha Hurley-Walker, who is from the Curtin University node of the International Centre for Radio Astronomy Research, led the team.&nbsp;

"This object was appearing and disappearing over a few hours during our observations. That was completely unexpected. It was kind of spooky for an astronomer because there's nothing known in the sky that does that. And it's really quite close to us -- about 4000 lightyears away. It's in our galactic backyard," she said.&nbsp;

A student named&nbsp;Tyrone O'Doherty from Curtin University discovered the object by using the Murchison Widefield Array (MWA) telescope in outback Western Australia. He also used a new technique developed by him.

O'Doherty, who is now studying for a PhD at Curtin, said, "It's exciting that the source I identified last year has turned out to be such a peculiar object."

"The MWA's wide field of view and extreme sensitivity are perfect for surveying the entire sky and detecting the unexpected," he added.&nbsp;

Images of “blue lightning” in space captured in February 2019 are making the rounds on the internet after finding mention in a new study.

But what is “blue lightning”? It simply refers to thunderstorms outside of our vision from Earth, which may be visible from space.

The image in question is from thunderclouds above the Pacific island of Nauru. Last week, a paper published in Nature shed light on this phenomenon.

Spearheaded by the Atmosphere-Space Interactions Monitor (ASIM), the team used a collection of cameras with visible and ultraviolet spectrum light detectors, along with X-ray and gamma-ray detectors to fish out electrical interactions that take place above thunderclouds.

The goal was to capture space lightning - blue jet, along with four complementing flashes on the top the clouds.

These stormy flashes stayed in the first layer of the atmosphere called troposphere instead of settling in the second layer of the atmosphere called stratosphere.

Blue jets continue to remain elusive to scientists, but they believe it’s a result of electric breakdown which takes place between positively charged and negatively charged sections of storm clouds.

The four small flashes that joined the blue jet are commonly known as “elves”, which stands for Emissions of Light and Very Low Frequency Perturbations due to Electromagnetic Pulse Sources.

Elves are essentially flashes of light that are produced when negatively charged electrons are pushed through a part of the atmosphere known as ionosphere by radio waves.

Blue jets still remain largely misunderstood, and there’s a lot that we still don’t know about these beautiful light shows.
