There are more than 5,000 known worlds beyond our solar system.
Since the 1990s, astronomers have used ground- and space-based telescopes to search for signs of planets beyond our smallest corner of the universe.
Exoplanets are notoriously difficult to image directly because they are so far from Earth.
But scientists know the signs, looking for the wobbles of stars as orbiting planets use their own gravitational pull, or dips in starlight as planets pass in front of their star trains.
It is very likely that there are more than a hundred billion exoplanets just waiting to be discovered.
Part of the excitement around the James Webb Space Telescope is the ability to peer inside the atmospheres of potentially habitable planets and discover new worlds. This week, at least the space watcher has been delivered.
The Webb Telescope confirmed the existence of an exoplanet for the first time since the space observatory was launched in December 2021.
A world such as LHS 475 b is roughly the same size as Earth and recedes 41 light years in the constellation Octanes.
Scientists cannot yet determine if the planet has an atmosphere, but the telescope’s capabilities have picked up on a wide range of molecules. Webb will do another crack this summer to observe the planet to build on this data.
An exoplanet is just one of the cosmic discoveries Webb announced this week at the American Astronomical Society in Seattle. What’s more, NASA’s Transiting Exoplanet Survey Satellite, or TESS, is a mission to find another Earth-sized exoplanet within 100 light years of planetary engineering — and a potentially habitable world.
A year after the powerful eruption of the Ha’apai Hunga Tonga-Hunga volcano, scientists are still learning about the most amazing events.
The explosion went on to produce more than 25,500 lightning strikes in just five minutes, according to a new report. The event also uses nearly 400,000 lightning strikes in six hours and accounts for half of all lightning strikes in the world during the peak of the eruption.
But what’s even more surprising is that the January 2022 eruption was only one moment in a year of lightning strikes around the world.
Blooming flowers are notoriously ephemeral, but a nearly 40-million-year-old specimen remains solidified in amber and time.
Researchers have found another type of extraordinary fossil amber, which was first documented in 1872. The main flower is known to be fossilized in amber at 1.1 inches (28 millimeters) across.
Scientists were able to extract some pollen from the flower and found it belonged to a group of modern plants.
Meanwhile, archaeologists discovered eight prehistoric ostrich eggs near an ancient fire pit in Israel.
Russian space propulsion Roscosmos will launch an unmanned space probe to the International Space Station as the return vehicle for the three-member crew after the Soyuz capsule suffered its loss in December.
Cosmonauts Sergey Prokopyev and Dmitri Petelin and NASA astronaut Frank Rubio were launched to the space station in September.
The commission said damage to the Soyuz radiator tube was caused by a micrometeoroid impact, which created a hole with a diameter of less than 1 millimeter, according to Roscosmos.
The crew members remain healthy, but their return to Earth – which has not been determined – will be delayed for at least several months.
Meanwhile, Virgin Orbit has attempted to launch its LauncherOne rocket from the United Kingdom, and California-based start-up ABL Space Systems has set out to launch its RS1 rocket from Alaska. Both rockets failed, and investigations were conducted to determine what had gone awry.
The contrails that pour down our skies every day after aircraft crisscrossing them may seem harmless, but such light clouds of ice are a very bad environment.
Condensation trails, which consist of ice crystals clustered around small particles fired by guns, generate more heat than the carbon dioxide emissions that result from burning fuel. The length of the contrails depends on the atmospheric conditions.
Researchers believe that slightly different specific flight paths can help reduce damage.
