Scientists head out to the Gulf of Mexico every summer to measure the size of the dead zone—an area with oxygen levels that are too low to support most marine life.
The Trifid Nebula is a stellar nursery, a cluster of recently born stars, a bright red hydrogen emission nebula, a lovely blue reflection nebula, and an interesting dark nebula divided into 3 …
What would it be like to view the Earth and the sky from the vantage point of the International Space Station? These three photos from ISS tell the tale.
Between July 20 and 22, 2014, the Cassini spacecraft – which has been orbiting Saturn since 2004 – tracked a system of clouds developing, then dissipating over a methane sea on Saturn’s large moon, Titan. Earthly scientists call this alien northern sea on Titan by the name Ligeia Mare.
We now know more than 1,800 exoplanets – worlds orbiting distant suns – but zero exomoons. UT Arlington physicists propose a new way to search for them, based on the behavior of one our solar system’s strangest moon’s, Io.
It’s the insect star of The Silence of the Lambs.
Astronomers are scrutinizing a star system in a distant galaxy that exploded, possibly leaving behind a zombie star. They say their study of this system will help them understand supernova explosions, which are an important piece of the cosmic puzzle, used to help measure distances in vast space and the expansion of the universe.
Astronomers in Hawaii said they were “surprised” by the many bright, swirling storms they observed this week on the planet Uranus, including at least one “monstrous feature.” It just goes to show we haven’t had the equipment to observe Uranus as carefully as we now can, throughout its 84-year orbit.
Two storms are laying siege to Hawaii today: Iselle and Julio. Iselle was downgraded to a tropical storm as its winds battered Hawaii’s Big Island on Thursday night. The center of the storm had been expected to make landfall Thursday, but remained offshore hours after it had been expected to strike. On its current path, Iselle will deliver a direct hit to Big Island of Hawaii and pass just south of the other islands. Hurricane Julio, with winds of over 100 miles per hour, is close behind. It is expected to reach the Hawaiian Islands over the weekend.
Have you ever been in a hot city in the middle of summer then driven to the country where it is noticeably cooler? That extra heat in the city is what scientists refer to as the urban heat island effect. And humid cities across North America have it worse than dry ones, according to a new study.
