The Breakthrough Listen Investigation for Periodic Spectral Signals (BLIPSS), led by Akshay Suresh, Cornell doctoral candidate in astronomy, is pioneering a search for periodic signals emanating from the core of our galaxy, the Milky Way. The research aims to detect repetitive patterns, a way to search for extraterrestrial intelligence (SETI) within our cosmic neighborhood.

The researchers developed software based on a Fast Folding Algorithm (FFA), an efficient search method offering enhanced sensitivity to periodic sequences of narrow pulses. Their paper, “A 4–8 GHz Galactic Center Search for Periodic Technosignatures,” was published May 30 in The Astronomical Journal.

Pulsars—rapidly rotating that sweep beams of radio energy across the Earth—are natural astrophysical objects that generate periodic signals but humans also use directed periodic transmissions for a variety of applications, including radar. Such signals would be a good way to get someone’s attention across , standing out from the background of non-periodic signals, as well as using much less energy than a transmitter that is broadcasting continuously.

In this video, Unveiled takes a closer look at the real reason why aliens WILL kill humankind! For decades, our species has debated and prepared for first contact… but real life isn’t like the movies. When aliens arrive, will we REALLY stand a chance of fighting them off? Of making peace? Or would we all be wiped out before we even knew they were here??

This is Unveiled, giving you incredible answers to extraordinary questions!

but live a different life, and make different decisions resulting in a totally different outcome in each universe.

We know this as the multiverse. But where did the idea for multiple universes come from?

Today we’re going to confront the idea of the existence of a multiverse as recent discoveries in physics and astronomy could point to their existence. Have we finally found evidence for a parallel universe, or is it something stranger we cannot comprehend?

Whenever we open a new window on the universe, we discover things that no one expected. Our newfound ability to measure ripples in the fabric of spacetime—gravitational waves—is a very new window, and so far we’ve seen a lot of wild stuff. We’ve observed black holes colliding, and their oddly high masses challenges our understanding of black hole formation and growth. We’ve seen colliding neutron stars that have forced us to rewrite our ideas of how many of the elements of the periodic table get made. But what else might be hiding in the ripples’ of spacetime? Oh, I know: how about the gravitational wakes caused by planet-sized alien spacecraft accelerating to near light speed.

Our homes are the places that define us; those warm private spaces that we depend on for work, respite, and haven from the harsh realities of the wider world. On Earth, the buildings and dwellings humans spend the majority of their lives in serve as reflections of our society’s culture, beliefs, and values. So if the shelters we make for ourselves truly mirror and influence our everyday lives, how might that sentiment be translated to living in space?

The kinds of structures future explorers might live in on other planets may be more critical to space exploration than sci-fi depictions of cities and homes in a galaxy far, far away suggest. As NASA’s desire for long-term human space colonization comes to fruition with planned crewed missions to Mars, establishing safe and well-made human settlements for life off-Earth is one of the agency’s most urgent tasks.

Putting down roots on Mars is an extremely ambitious goal to accomplish this century — but the reason why isn’t to do with rockets, necessarily. Rather, it is because any human settlement on the Red Planet will have to fight tooth and nail to experience even a modicum of ecological success.

Most of Mars appears to be an endless expanse of alien desert, without a river or lake in sight. However, liquid water definitely existed in the planet’s distant past. A new paper has also suggested that it’s also possible small quantities of water still might exist in places that otherwise appear barren.

Before China’s Zhurong (also known as Phoenix) rover went into hibernation mode last May, researchers from the National Astronomical Observatories and the Institute of Atmospheric Physics of the Chinese Academy of Sciences discovered something unexpected. Zhurong was exploring the Utopia Planitia region, which is near the planet’s equator. No liquid water was thought to exist at those latitudes. Yet when the rover beamed back data from its Multispectral Camera (MSCam), Navigation and Terrain Camera (NaTeCam), and Mars Surface Composition Detector (MarSCoDe), there was possible evidence for liquid water having been present less than half a million years ago.

“[Our findings] suggest [features] associated with the activity of saline water, indicating the existence of water process on the low-latitude region of Mars,” the researchers said in a study recently published in Science Advances.
