Water on Mars may have flowed for a billion years longer than thought

Observations by a long-running Mars mission suggest that liquid water may have flowed on the Red Planet as little as 2 billion years ago, much later than scientists once thought. Scientists charted the presence of chloride salt deposits left behind by flowing water using years of data from NASA’s Mars Reconnaissance Orbiter (MRO), which has … Read more

55 years after Apollo 1 fire, NASA’s lessons live on as Orion aims for the moon

NASA’s last moonbound program for astronauts lifted off under the shadow of a fatal incident on the Apollo 1 spacecraft, 55 years ago today (Jan. 27). Apollo 1 was expected to fly to Earth orbit later in 1967 with astronauts Gus Grissom, Roger Chaffee and Ed White on board. During a test on the launch … Read more

Could a spacecraft ‘catch up’ to interstellar visitor ‘Oumuamua in just 26 years?

Could we send a spacecraft to the giant, cigar-shaped interstellar interloper ‘Oumuamua? Should we? In 2017, astronomers detected a space rock from another solar system whizzing through our cosmic neighborhood for the first time ever. The rock, called ‘Oumuamua, passed us by and sailed through our solar system leaving behind questions that remain to this … Read more

5,000 possible alien worlds in less than 4 years for NASA planet-hunting mission

It’s been a busy four years for NASA’s Transiting Exoplanet Survey Satellite (TESS) and the scientists who seek planets in its data. The mission just hit a major discovery milestone, passing 5,000 of what the team calls TESS Objects of Interest, or TOIs, which include exoplanet candidates and other intriguing signals. Astronomers select objects from … Read more

Mysterious Effects of Smoking May Surface Even 3 Generations Later, Study Finds

The great-granddaughters of men who smoked cigarettes when they were pre-pubescent boys are more likely to carry excess fat on their bodies as young women several decades later, a rather startling study has found.   The discovery – which scientists claim is one of the “first human demonstrations of transgenerational effects of an environmental exposure … Read more

Mars ‘asteroid showers’ have stayed steady over 600 million years

Our dating assumptions for the Red Planet might need a second look. Fresh analysis of craters on Mars suggests that asteroids have been smashing into the surface at a consistent rate for at least 600 million years. Scientists often use craters as a proxy to figure out how old a planetary surface is, since more … Read more

Physicists Detect Mysterious X Particles in ‘Primordial Soup’ For The First Time

A mysterious particle thought to have existed briefly just after the Big Bang has now been detected for the first time in the ‘primordial soup’. Specifically, in a medium called the quark-gluon plasma, generated in the Large Hadron Collider by colliding lead ions. There, amid the trillions of particles produced by these collisions, physicists managed … Read more
