First detection of CO2 in atmosphere of exoplanet
Posted by Future Timeline in categories: space, sustainability
The planet is 1.27 times the diameter of Jupiter but has only 28% of its mass. It orbits just 0.0486 AU (7.3 million km) from its star, taking only 4.1 days to complete one “year” and resulting in a temperature of 900°C (1,600°F).
The parent star WASP-39 is of spectral class G – the same type as our own Sun – and just slightly smaller than the Sun. The system is 698 light years from Earth in the Virgo constellation.
Previous observations from telescopes including Hubble and Spitzer revealed the presence of water vapour, sodium, and potassium in the planet’s atmosphere. Last month, it became the first exoplanet to be studied by the recently launched James Webb Space Telescope (JWST) and this week NASA released the data from those observations. Webb’s unmatched infrared sensitivity has now confirmed the presence of carbon dioxide on this planet as well.
Researchers plan to use the James Webb Space Telescope for further observations.
An international team of researchers led by the University of Montreal discovered an exoplanet that could be covered entirely in water. The planet TOI-1452b is about 100 light years away from Earth, located in Draco Constellation. It’s larger in size and mass compared to Earth and is located in the “habitable zone,” which means the temperature is just right for the liquid water to exist. The team believes that it could be an “ocean planet,” a planet covered by a thick layer of water.
What’s so special about this ocean planet?

A Sheep, A Dog And Four Tiny ‘Humans’ Are About To Go To Space As NASA’s Moon Mission Prepares For Blast-Off
Posted by Gemechu Taye in category: space
Two much-loved characters and some LEGO minifigures have been assigned to NASA’s Artemis I mission to the Moon. Shaun The Sheep and Snoopy are scheduled to lift-off during a two-hour window that opens at 8:33 a.m. EDT on Monday, August 29. If all goes to plan they’ll flyby the Moon and eventually return to Earth in the Orion spacecraft 42 days later.
This won’t be Snoopy’s first trip to space, having orbited Earth in a Space Shuttle in 1990. Snoopy will go to space this time as a visual indicator when a spacecraft has reached the weightlessness of microgravity. Interior cameras will capture the moment when Snoopy floats.
In the abscence of humans on NASA’s Artemis-1 mission around the Moon a cute selection of pop dolls, characters and “moonikins” will go to space.

The Space Launch System is an American super heavy-lift expendable launch vehicle under development by NASA since 2011. As of April 2022, the first launch is scheduled for no earlier than August 2022, pending the success of a wet dress rehearsal test.

NASA is joining the hunt for ‘unidentified aerial phenomena’
Posted by Gemechu Taye in category: space
The long-awaited Artemis I launch is almost here! You are invited to a Launch Watch Party at INFINITY Science Center scheduled for Monday, Aug. 29, from 7:00 – 10:00 a.m. The two-hour launch window opens at 7:33 a.m. CDT. We’ll have fun NASA activities such as coloring stations, build an Orion Capsule, draw Artemis, design your own patch, and much more!

Fast-growing sunspot may threaten Earth with flares and eruptions
Posted by Shubham Ghosh Roy in category: space
A once-tiny spot on the sun’s surface grew over the weekend to the size of Earth, potentially threatening our planet with radio blackout-causing solar flares and plasma eruptions that could trigger aurora displays.
The sun has been lively in the past few weeks, treating skywatchers at high latitudes and astronauts onboard the International Space Station to beautiful aurora displays. There may be more of those storms to come, as the sunspot AR3085 keeps growing and rotating toward Earth.

First underground radar images from Mars Perseverance Rover reveal some surprises
Posted by Saúl Morales Rodriguéz in category: space
After a tantalizing year-and-a-half wait since the Mars Perseverance Rover touched down on our nearest planetary neighbor, new data is arriving—and bringing with it a few surprises.
The rover, which is about the size of car and carries seven scientific instruments, has been probing Mars’ 30-mile-wide Jezero crater, once the site of a lake and an ideal spot to search for evidence of ancient life and information about the planet’s geological and climatic past.
In a paper published today in the journal Science Advances, a research team led by UCLA and the University of Oslo reveals that rock layers beneath the crater’s floor, observed by the rover’s ground-penetrating radar instrument, are unexpectedly inclined. The slopes, thicknesses and shapes of the inclined sections suggest they were either formed by slowly cooling lava or deposited as sediments in the former lake.
