Two years ago, astronomers believe they detected a star devouring one of its planets. Now, new observations of the aftermath of same event from the James Webb Space Telescope have suggested a scenario previously only considered in the realms of science fiction: that a planet about the size of JupiterContinue Reading
Satellite observations had shown alternating stripes of light-colored and dark-colored rock in this area. In late March, Perseverance excavated one of the light-colored formations and collected a sample. In the process it discovered the strange rock—which has been named “St. Paul’s Bay.” A photo of the St. Paul’s Bay rock,Continue Reading
The original version of this story appeared in Quanta Magazine. At the beginning of time and the center of every black hole lies a point of infinite density called a singularity. To explore these enigmas, we take what we know about space, time, gravity, and quantum mechanics and apply itContinue Reading
Astronomers have found one of the most promising indications that there could be extraterrestrial life on another planet. With the help of the James Webb Space Telescope, researchers have detected what they believe could be biosignatures of marine microorganisms on K2-18b, an exoplanet located in the habitable zone of itsContinue Reading
It’s often the case that the more that planets are studied and understood, the more remote the possibility of inhabiting them seems. Mars, for example, is the closest celestial body to Earth in terms of distance, but data shows its conditions are extremely hostile for life. Despite this, NASA hasContinue Reading
Although the Leonids produce fewer meteors than many other of the major meteor showers, they are known for producing fast-moving, bright, fireball meteors. The Leonids peak just before the new moon—on the morning of November 18, the moon will be just 6 percent illuminated and in the eastern US won’tContinue Reading
SpaceX is having trouble with Starship’s upper stage after back-to-back failures, but engineers are making remarkable progress with the rocket’s enormous booster. The most visible sign of SpaceX making headway with Starship’s first stage—called Super Heavy—came at 9:40 am local time (10:40 am EDT; 14:40 UTC) Thursday at the company’sContinue Reading
