Terminators of planets caught in a gravitational trap can become a refuge for living beings
(ORDO NEWS) — Some exoplanets are always turned to their star with only one side – about the same as our Moon in relation to the Earth. American astronomers believe that the light division lines on these planets can still be inhabited. About 70 percent of the stars in the night sky are so-called M-dwarfs…

Entire planets made of dark matter could exist. Here’s how we can find them
(ORDO NEWS) — We may not have found many planetary systems like our solar system. However, they do have one thing in common: they seem to be made from the good old baryonic matter that makes up our planetary system. But what if there are planets made of other material: particles outside the Standard Model?…

Some planets may be made of dark matter, astrophysicists say
(ORDO NEWS) — Perhaps astronomers have discovered not many planetary systems like our solar system. However, they seem to have one thing in common: they seem to be formed from ordinary baryonic matter (consisting of neutrons, protons, and electrons). But what if there are planets made of other material? What if there are planets made…

Planets can protect their water until their star settles down, planetologists say
(ORDO NEWS) — Scientists at the University of Cambridge in the UK have created a complex model that describes a world in which most of the water is deep below the surface, not in pools or oceans, but in rocks. Technically, it’s in the minerals deep below the surface. If conditions are right on the…

2 new giant gas planets discovered
(ORDO NEWS) — Astronomers have reported the discovery of two new gas giants, TOI-3984A b and TOI-5293A b, which have very short orbital periods. The exoplanets were discovered by NASA‘s Transiting Exoplanet Survey Satellite (TESS), which tracks transit events by surveying some 200,000 of the brightest stars near the Sun. A transit occurs when a…

Stars can swallow and eject planets
(ORDO NEWS) — As unfortunate as it may be, the absorption of a planetary object by its stellar parent is a common scenario throughout the universe. But this does not necessarily have to end in the death of a celestial body. A team of astrophysicists used computer simulations and found that planets can not only…

Astronomers use ‘little hurricanes’ to weigh and date planets
(ORDO NEWS) — The small “hurricanes” that form in the disks of gas and dust around young stars could help study certain aspects of planet formation. Researchers at the University of Cambridge have developed a technique that uses observations of these “hurricanes” to establish some limits on the mass and age of planets in a…

Presence of oxygen on other planets does not necessarily mean that there is life there
(ORDO NEWS) — Scientists have proven that oxygen can be produced in large quantities not only as a result of the activity of microorganisms, but also due to powerful volcanic activity on “dead” worlds.

After all, oxygen may not be a perfect sign of life on other planets
(ORDO NEWS) — The detection of oxygen in an exoplanet’s atmosphere could indicate the existence of life. On Earth, photosynthetic organisms take in carbon dioxide, sunlight, and water and produce sugars and starches for energy. Oxygen is a by-product of this process, so if we can find oxygen elsewhere, it will cause a stir. But…
