Mars shows how even the simplest life forms can destroy their own planet

Mars shows how even the simplest life forms can destroy their own planet

The second model sought to identify the physical and chemical characteristics of Mars’s porous crust – namely, temperature, chemical composition, and the presence of liquid water. These were partly determined by surface conditions (ie, surface temperature and atmospheric composition) and partly by the planet’s internal characteristics (ie, internal thermal gradient and crust porosity). These first … Read more

The bringer of nightmares, the undead and the zombie planets |  Life

I t is widely accepted among the scientific community that over the next few billion years the sun will swell into a red giant star, absorbing Mercury and Venus, and cauterizing the Earth. Then the sun will sneeze off its outer layers, becoming a white dwarf star, which will be so miserly with its energy … Read more

Is our planet surrounded by a giant magnetic tunnel? let’s find out

Is our planet surrounded by a giant magnetic tunnel?  let’s find out

“If we were to look up in the sky,” West explains, “we would see this tunnel-like structure in just about every direction we looked – that is, if we had eyes that could see radio light.” Called “the North Polar Spur” and “the Fan Region,” we’ve known about these two structures for a long time. … Read more

Telescope shows dancing stars making beautiful ripples of dust |  Life

The amazing images produced so far by the James Webb Space Telescope (JWST) have captured the media. They are easy to find online; just search for James Webb Space Telescope pictures. A very interesting new one has just been released. It shows what looks rather like a fingerprint in space. To see it, look at … Read more

Planet With the ‘Density of a Marshmallow’ Spotted Around Red Dwarf Star

The National Science Foundation says TOI-3757 b (right) is the fluffiest gas giant exoplanet to orbit a gas giant.Drawing: NSF NOIRLab Space has no shortage of weird and curious planets. HASstronomers using the 3.5-meter telescope at Kitt Peak National Observatory report their discovery of a Jupiter-like world with roughly the same density as a marshmallow, … Read more

Earth’s next supercontinent will form in the next 200-300 million years

Earth’s next supercontinent will form in the next 200-300 million years

According to the calculations made by the researchers, the younger oceans, such as the Atlantic and the Indian Ocean, are unlikely to close in the next round of tectonic plate movements. Interestingly, the continent of Australia will also have a role to play, as it is expected to collide with Asia first before Amasia formation … Read more

Astronomer develops new method for spotting elusive newborn planets

Astronomer develops new method for spotting elusive newborn planets

“This arc and clump are separated by about 120 degrees,” she explained. “That degree of separation doesn’t just happen — it’s mathematically important.” Unfortunately, the small, newborn planet cannot yet be directly imaged due to technological limitations, but Long hopes additional future ALMA observations of LkCa 15 will provide further evidence supporting her planetary discovery. … Read more

Don’t miss Jupiter’s closest date with Earth in 70 years on Sep 26

Don’t miss Jupiter’s closest date with Earth in 70 years on Sep 26

Washington: Jupiter is set to make its closest approach to Earth in the last 70 years and on September 26, stargazers can expect an excellent view when the giant planet reaches opposition. From the viewpoint of Earth’s surface, opposition happens when an astronomical object rises in the east as the Sun sets in the west, … Read more
