New mission will explore the possibility of alien life in Alpha Centauri



Alpha Centauri is the closest star system to our own, only four light-years away. It consists of three stars: Alpha Centauri A and B, which are similar to the Sun, and Proxima Centauri, a red dwarf that hosts the nearest known exoplanet, Proxima b. Could there be other planets orbiting these stars, perhaps even ones that could support life?

A new satellite mission aims to find out. The mission is called TOLIMAN, after the ancient Arabic name for Alpha Centauri. It is a collaboration between the University of Sydney and EnduroSat, a Bulgarian company that specializes in micro-satellites.

The mission is also supported by Breakthrough Initiatives, a philanthropic organization that funds projects related to the search for extraterrestrial intelligence.

The goal of TOLIMAN is to detect Earth-like planets in the habitable zone of Alpha Centauri A and B, the region where liquid water could exist on the surface.

To do this, the mission will use a technique called astrometry, which measures the tiny wobbles of stars caused by the gravitational pull of their planets.

This method is complementary to other techniques such as transit photometry and radial velocity, which look for dips in starlight or shifts in star spectra due to planetary orbits.

TOLIMAN will employ a custom-designed space telescope that will fit inside a 12-liter cube. The telescope will have a high-resolution camera and a coronagraph, a device that blocks out the bright light of the stars to reveal their fainter companions.

The telescope will also use a novel optical system called aperture masking interferometry, which combines the light from different parts of the telescope’s mirror to create interference patterns that reveal information about the star system.

The mission will launch in 2024 and orbit the Earth for two years. During this time, it will observe Alpha Centauri A and B for about 20 minutes every day, collecting data that will be analyzed by scientists on the ground.

The mission hopes to achieve an astrometric precision of 10 microarcseconds, which is equivalent to measuring the width of a human hair from 500 kilometers away.

If TOLIMAN succeeds in finding planets around Alpha Centauri A and B, it will open up new possibilities for further exploration and characterization. For instance, future missions such as James Webb Space Telescope or Breakthrough Starshot could target these planets for spectroscopic analysis or direct imaging, looking for signs of atmospheres, oceans, or even life.

TOLIMAN is an ambitious and innovative mission that will push the boundaries of satellite technology and exoplanet science. It will also bring us closer to answering one of the most profound questions in human history: are we alone in the universe?

“Alien bases” may be hiding off the coast of Alaska, researchers say




An organization of civilian volunteers dedicated to the study of
unidentified flying objects (UFOs) has issued a statement based on
decades of studying eyewitness reports. According to Mutual UFO Network,
“alien bases” may be hiding off the coast of Alaska, reports

say the deep waters in this region may hold something surprising. After
analyzing reports from the ship’s crew from 1945, they hypothesized
that alien objects could be lurking underwater, off the coast of the

Alleged sightings of alien spacecraft nearly 80 years ago
have become a key point in research. Members of the organization believe
that UFOs move over water and may have “bases.”

allege crew members on a U.S. Army transporter ship sailing past Island
Adak saw a massive UFO sized 150 to 200 feet emerge from the water.
Although these reports are nowhere to be found, UFO enthusiasts believe
the unidentified flying vehicles likely were used to commute to
different supposed alien bases hiding in the deep waters.

the “secret reports” of the sailors aren’t available, investigators
have taken it upon themselves to unravel the mystery surrounding the
unidentified flying objects and they believe the ocean has alien bases
that humans aren’t aware of.

Enthusiasts claim that UFOs may be
using “underwater networks” or wormholes as superhighways to travel
between points in the universe. UFO researcher Johnny Enoch added that
such objects could serve as a vehicle for aliens.

There are also
theories that other places on Earth could serve as bases for alien life.
A mountain in Seoul, South Korea is believed to be hiding a UFO,
according to Dr. Steven Greer.

An episode of the series “The
Alaska Triangle” features satellite imagery that claims to show one of
the “alien bases” in the Pacific Ocean off the coast of California.

another researcher featured in the program showed markings from the sea
bed that she claimed could have been roadways for aliens.

the mysteries of the ocean remain unsolved, researchers continue their
search, trying to unravel the mystery of what may be hiding in the
depths of the waters off the coast of Alaska.

Enormous City-Size Comet Racing Towards Earth Grows ‘Devil Horns’ After Massive Eruption




A volcanic comet the size of a mid-sized US city has
violently exploded for the second time in four months as it continues
racing toward the earth. And following the massive eruption, the cloud
of ice and gas sprouted what looked like a pair of gigantic devil horns.

The city-sized comet, named 12P/Pons-Brooks, is a cryovolcanic — or
cold volcano — comet. It has a solid nucleus, with an estimated diameter
of 18.6 miles, and is filled with a mix of ice, dust and gas known as
cryomagma. The nucleus is surrounded by a fuzzy cloud of gas called a
coma, which leaks out of the comet’s interior.

When solar radiation heats the comet’s insides, the pressure builds up
and the comet violently explodes, ejaculating its ice-cold innards into
space through seeping cracks in the nucleus’s shell.

Live Science report:
On Oct. 5, astronomers detected a large outburst from 12P, after the
comet became dozens of times brighter due to the extra light reflecting
from its expanded coma, according to the British Astronomical Association (BAA), which has been closely monitoring the comet 

Over the next few days, the comet’s coma expanded further and developed its “peculiar horns,”
reported. Some experts joked that the irregular shape of the coma also
makes the comet look like a science fiction spaceship, such as the
Millennium Falcon from Star Wars.

The unusual shape of the comet’s coma is likely due to an irregularity in the shape of 12P’s nucleus, Richard Miles, a BAA astronomer, told Live Science after the comet’s previous eruption.
The outflowing gas is likely being partially obstructed by a notch
sticking out on the nucleus, Miles said. As the gas continues to expand
away from the comet, the irregularity in the coma’s shape becomes more
defined and noticeable, he added.

12P is currently hurtling toward the inner solar system, where it
will be slingshotted around the sun on its highly elliptical 71-year
orbit around our home star — similar to the green comet Nishimura, which
pulled off a near-identical maneuver on Sept. 17

12P will reach its closest point to Earth on April 21, 2024, when it
may become visible to the naked eye before being catapulted back toward
the outer solar system. It will not return until 2095.

This is the second time 12P has sprouted its horns this year. On July
20, astronomers witnessed the comet blow its top for the first time in
69 years (mainly due to its outbursts being less frequent and harder to
spot during the rest of its orbit). On that occasion, 12P’s coma grew to
around 143,000 miles (230,000 km), which is around 7,000 times wider
than the comet’s nucleus.

It is unclear how large the coma grew during the most recent
eruption, but there are signs the outburst was “twice as intense” as the
previous one, the BAA noted. By now, the coma has likely shrunk back to
near its normal size.

As 12P continues to race toward the sun, there is a high probability
that we will witness several more major eruptions. It is possible that
those eruptions will be even bigger than the most recent one as the
comet soaks up more solar radiation, according to

But 12P is not the only volcanic comet that astronomers are currently
monitoring: 29P/Schwassmann-Wachmann (29P) — the most volatile volcanic
comet in the solar system — has also had several noticeable eruptions
in the last year.

In December 2022, 29P experienced its largest eruption in around 12 years, which sprayed around 1 million tons of cryomagma into space. And in April this year, for the first time ever, scientists accurately predicted one of 29P’s eruptions before it actually happened, thanks to a slight increase in the comet’s brightness in the lead-up to the icy explosion.
