there is Over 5,000 known worlds beyond our solar system.
Since the 1990s, astronomers have used telescopes on the ground and in space to look for signs of planets beyond the tiny corners of space.
Exoplanets are notoriously difficult to image directly because they are so far away from Earth.
But scientists know the signs, looking for stars to wobble when orbiting planets use their gravity, or for planets to sink into starlight as they pass in front of their stellar hosts.
It is very likely that there are hundreds of billions more exoplanets waiting to be discovered.
Part of the excitement of the James Webb Space Telescope Peering into the atmosphere of a potentially habitable planet and discover new worlds. The space observatory certainly delivered this week.
The Webb Telescope has confirmed the existence of an exoplanet for the first time since the space observatory launched in December 2021.
Known as LHS 475 b, this world is about the size of Earth and is located 41 light-years away in the constellation Octane.
Scientists cannot yet determine whether the planet has an atmosphere, but The telescope’s sensitive ability picked up a variety of moleculesWebb will get another crack at observing planets based on this data this summer.
Exoplanets are just one of Webb’s cosmic discoveries announced at the American Astronomical Society in Seattle this week. In addition, NASA’s Transiting Exoplanet Survey Satellite (TESS) mission Second Earth-sized exoplanet in intriguing planetary system A world 100 light-years away could become habitable.
A year has passed since the powerful eruption of the Hunga Tonga-Hunga Ha’apai volcano, and scientists are still learning about the event’s more astonishing aftereffects.
A new report says the blast caused more than 25,500 lightning strikes in just five minutes. The event also caused approximately 400,000 lightning strikes in six hours, accounting for half of all lightning strikes worldwide at the peak of the eruption.
But even more surprising is that the January 2022 eruption Just one factor in years of extreme lightning in the world.
Blooming flowers are known to be ephemeral, but nearly 40-million-year-old specimens have been trapped in amber and frozen over time.
Researchers have once again examined an extraordinary amber fossil first recorded in 1872. Largest known flower fossilized in amber 1.1 inches (28 millimeters) wide.
Scientists have been able to extract part of the flower pollen and have discovered that it is related to a group of modern plants.
Meanwhile, archaeologists have discovered Eight prehistoric ostrich eggs near an ancient fire pit in Israel.
Russian space agency Roscosmos will launch an unmanned exchange spacecraft to the International Space Station as a return vehicle for a three-man crew after the Soyuz capsule was damaged in December.
Astronauts Sergei Prokopiev and Dmitry Petelin and NASA astronaut Frank Rubio launched to the space station in September.
The commission said that damage to the Soyuz radiator pipeline caused by a micrometeorite impactA hole less than 1 mm in diameter was created, according to Roscosmos.
The crew remains in good health, but a return to Earth has not been determined, but will be delayed by at least a few months.
in the meantime, Virgin Orbit’s LauncherOne rocket attempted to launch from Englandand California-based startup ABL Space Systems, Launch an RS1 rocket from AlaskaBoth rockets failed and an investigation is underway to determine the cause.
Contrails drifting behind the aircraft that cross our skies every day may seem harmless, but these wispy ice clouds are actually bad for the environment.
Condensation trails, formed by ice crystals gathering around tiny particles emitted by jet engines, trap more heat than the carbon dioxide released from burning fuel. Contrail lifetime depends on atmospheric conditions.
Researchers Slightly deviate the path of certain flights Damage can be reduced.
