We may finally find ALIENS by 2026, thanks to NASA’s new space telescope

Published

(Planet Today) The National Aeronautics and Space Administration‘s (NASA) James Webb Space Telescope (JWST) may be able to provide evidence of aliens as early as 2026. This is according to Caprice Phillips of the Ohio State University, who found with her colleagues that Webb can detect signs of alien life in three days or so. Phillips said that after a few orbits, the telescope will have collected enough data to tell whether aliens exist.

“What really surprised me about the results is that we may realistically find signs of life on other planets in the next five to 10 years,” Phillips remarked. She presented their findings during the American Physical Society April Meeting.

NASA telescope facilitates search for alien life

When searching for alien life, some of the most promising planets to explore are gas dwarfs. Also called mini-Neptunes, gas dwarfs are up to four times as big as Earth and have a rocky core, unlike gas giants such as Jupiter. They are less massive than Neptune but have the same hydrogen- and helium-rich atmosphere, which have the potential to support life.

Astronomers look for biosignatures – chemical footprints that point to the presence of organisms – when hunting for aliens. But performing such searches on gas dwarfs are not easy since these worlds do not exist in our solar system. Scientists have to observe exoplanets, or worlds that orbit a star other than the sun. Unfortunately, exoplanets are too far away and existing observatories are not powerful enough to make precise observations.

But NASA’s newest telescope may just do the job. Deemed as the successor to the Hubble Space Telescope, the agency’s longtime eyepiece into the cosmos, Webb is the largest, most powerful space observatory ever built. It can peer farther back into time than Hubble is capable of doing, thanks to its much larger mirror.

For their study, Phillips and her team simulated Webb observations to examine how well the telescope detects ammonia, a potential biosignature, on seven potentially habitable gas dwarfs. The researchers incorporated various cloud conditions into planetary models to quantify how significant Webb’s detection is.

The simulation showed that Webb could detect ammonia in as little as 60 hours. After about ten orbits around the sun, the observatory would have collected enough data to determine whether aliens live on a gas dwarf. 

“Humankind has contemplated the questions, ‘Are we alone? What is life? Is life elsewhere similar to us?”’ Phillips remarked. “My research suggests that for the first time, we have the scientific knowledge and technological capabilities to realistically begin to find the answers to these questions.”

A primer on James Webb Space Telescope

Webb will be launched into space in October 31, 2021. It will orbit the sun around a million miles from Earth, but will take as long as the planet to complete an orbit.

“What is special about this orbit is that it lets the telescope stay in line with the Earth as it moves around the sun,” NASA said. “This allows the satellite’s large sunshield to protect the telescope from the light and heat of the sun and Earth.”

The observatory will be mainly used for studying the history of the universe, beginning from the Big Bang to the formation of star systems that are capable of supporting life. Scientists also plan to avail of Webb to study a host of other things, including dark matter.

Richard Massey, a professor of cosmology at Durham University in the U.K., is part of a team that is working to understand what dark matter is.

“Dark matter is invisible. But in this same patch of sky, we used the Hubble Space Telescope to make the first 3D map of dark matter, by noticing how it affects all the visible things around it. Now, the JWST will zoom in on individual clumps of dark matter with unprecedented resolution.”

‘October Surprise’: Russia To Launch Nukes in Space

Published

By


The ‘national security threat’ announced on Wednesday is
about Russia planning to launch nuclear weapons in space, causing some
to speculate whether it’s really an election year ploy.

The panic began when House Intelligence Committee Chair Mike Turner
(R-Ohio) asked President Biden to declassify information about a
“serious national security threat”.

Modernity.news reports: The weapon would reportedly be designed to be used to take out satellites.

Speaker Mike Johnson (R-La.) responded by telling reporters he wanted “to assure the American people, there is no need for public alarm.”

The big, scary threat is serious business and involves a space-based nuke controlled by evil dictator Putin, but it’s also “not an immediate crisis,” according to what three members of the U.S. House Intelligence Committee have told Politico.

Okay, then. Just for election season, is it?

Zero Hedge reports: “So, the question is – was this:

a) a distraction from Biden’s broken brain, or

2) a last desperate attempt to get more funding for anything-but-the-US-border, or

iii) a path to pitching Putin as the uber-bad-guy again after his interview with Tucker Carlson.”

Just by coincidence, Mike Turner recently returned from Ukraine having lobbied for billions more in weapons and aid for Zelensky’s government.

Some questioned the timing, suggesting it might all be a deep state plot to keep American voters afraid when they hit the ballot box.

Speculation will now rage as to whether this is “the event,” real or imagined, that billionaires and elitists the world over have been building underground survival bunkers in preparation for.

Earth has built-in protection from asteroids

Published

Asteroids are not just wandering space rocks, but a potential threat
to Earth. But what if the Earth already has its own built-in defenses
against them? Recent research published on the preprint server arXiv puts forward an unusual theory: Earth’s gravitational forces may serve as its secret shield against asteroids.

Our
planet uses powerful gravitational interactions with other celestial
bodies to break apart asteroids that approach it. These tidal forces,
akin to those that explain Earth’s tides caused by the Moon, can be so
intense that objects undergo tidal disruption, causing them to be torn
apart.

Observations of fragments of Comet Shoemaker-Levy 9 after
its collision with Jupiter in 1994 provided the first confirmation of
this phenomenon. However, for decades astronomers have been looking for
evidence that Earth or other terrestrial planets could have a similar
effect on asteroids and comets.

Planetary scientist Mikael Granvik
from the Swedish University of Technology, Luleå, led the research that
came closer to solving the above phenomenon.

His
discovery is linked to the search for gravitationally disrupted
near-Earth asteroids (NEAS), and provides compelling evidence that our
planet’s gravitational forces are not just an abstract concept, but a
factor capable of breaking asteroids into small pieces.

Based on
modeling of asteroid trajectories, Grunwick and colleague Kevin Walsh of
the Southwest Research Institute found that collisions with rocky
planets can cause asteroids to lose a significant portion of their mass,
turning them into debris streams.

New data shows that small
asteroid fragments, while not posing a threat to life on the planet, may
nevertheless increase the likelihood of local collisions like those
that occurred in Tunguska and Chelyabinsk.

Granwick assures that
asteroids smaller than 1 km in diameter are not a critical threat, but
increase the likelihood of incidents. However, it is worth remembering
the additional risks that may arise due to the formation of new debris
clouds.
