Wolf 1,069 b offers a unique opportunity to study a potentially habitable and tidally locked exoplanet and how life might evolve in such an environment.
A new exoplanet could be the next habitable zone that researchers have been looking for, according to a report.

In October 2015 Neil Turok, director of the Perimeter Institute for Theoretical Physics (PI) located in Waterloo, Canada opened the new season of the PI Public Lecture Series with a talk about the remarkable simplicity that underlies nature. Professor Turok, who was born in South Africa and now lives in Canada, discussed how this simplicity at the largest and tiniest scales of the Universe is pointing toward new avenues of research and revolutionary advances in technology.

Researchers at UCL and the University of Cambridge have discovered a new type of ice that more closely resembles liquid water than any other known ices and that may rewrite our understanding of water and its many anomalies.
The newly discovered ice is amorphous—that is, its molecules are in a disorganized form, not neatly ordered as they are in ordinary, crystalline ice. Amorphous ice, although rare on Earth, is the main type of ice found in space. That is because in the colder environment of space, ice does not have enough thermal energy to form crystals.
For the study, published in the journal Science, the research team used a process called ball milling, vigorously shaking ordinary ice together with steel balls in a jar cooled to-200 degrees Centigrade.

Sometimes to know what the matter is, you have to find it first. When the universe began, matter was flung outward and gradually formed the planets, stars and galaxies that we know and love today. By carefully assembling a map of that matter today, scientists can try to understand the forces that shaped the evolution of the universe.
A group of scientists, including several with the University of Chicago and Fermi National Accelerator Laboratory, have released one of the most precise measurements ever made of how matter is distributed across the universe today.
Combining data from two major telescope surveys of the universe, the Dark Energy Survey and the South Pole Telescope, the analysis involved more than 150 researchers and is published as a set of three articles Jan. 31 in Physical Review D.
The internet is abuzz with mentions of Comet C/2022 E3 (ZTF) a.k.a., the green comet, which on Wednesday could be seen with the naked eye.
As per NASA, the comet paid our planet a visit after a good 50,000 years. It was a rare feast for stargazers and astronomers alike as people around the globe witnessed the astronomical event.
With simulations that go into finer details than ever before, Brooke Polak of the University of Heidelberg and Hubert Klahr at the Max Planck Institute for Astronomy (MPIA) have modeled a key phase in the formation of planets in our solar system: the way that centimeter-size pebbles aggregate into so-called planetesimals tens to hundreds kilometers in size. The simulation reproduces the initial size distribution of planetesimals, which can be checked against observations of present-day asteroids. It also predicts the prevalence of close binary planetesimals in our solar system.
In a new study published on arXiv and accepted for publication in The Astrophysical Journal, astrophysicists Brooke Polak from the University of Heidelberg and Hubert Klahr from the Max Planck Institute for Astronomy used simulations to derive key properties of so-called planetesimals—the intermediate-size bodies from which planets formed in our solar system roughly 4.5 billion years ago.
Using an innovative method for simulating planetesimal formation, the two researchers were able to predict the initial size distribution of planetesimals in our solar system: how many are likely to have formed in the different “size brackets” between roughly 10 km and 200 km.
An international team of space scientists reports that the moon exerts a tidal impact on the plasmasphere. For their paper published in the journal Nature Physics, the group used data from multiple spacecraft over a nearly 40-year period to measure tidal perturbations in the plasmapause. Balázs Heilig, with the Institute of Earth Physics and Space Science, in Hungary, has published a News & Views piece in the same journal issue, explaining the nature of the plasmasphere and outlining the work in this new effort.
Early scientists found a connection between the tides and the movement of the moon thousands of years ago. More recent evidence suggests the moon’s pull acts on the ionosphere as well. In this new study, the researchers wondered if the moon might also have an impact on the plasmasphere.
The plasmasphere is a toroidal mass of plasma that surrounds the Earth. It lies beyond the ionosphere and is made up mostly of electrons and protons. Its particles are charged by the ionosphere, and its outer boundary is known as the plasmapause.
On Jan. 16, 2003 space shuttle Columbia left Earth for its 28th and last flight. Even though at the time building the International Space Station was the main goal of the shuttle program, STS-107 (Columbia’s final mission) emphasized pure research, according to Space.com.
The seven-member crew — Rick Husband, commander; Michael Anderson, payload commander; David Brown, mission specialist; Kalpana Chawla, mission specialist; Laurel Clark, mission specialist; William McCool, pilot; and Ilan Ramon, payload specialist from the Israeli Space Agency — had spent 24 hours a day doing science experiments in two shifts.
The seven astronauts on board Columbia were killed on Feb. 1, 2003 when the space shuttle broke up while it was returning to Earth.
