Mars InSight's 'Mole' Is Moving Again

The NASA lander's robotic arm seems to have helped its heat probe burrow almost 2 centimeters (3/4 of an inch) since last week.

Mars InSight's 'mole' is moving again

NASA's InSight spacecraft has used its robotic arm to help its heat probe, known as "the mole," dig nearly 2 centimeters (3/4 of an inch) over the past week. While modest, the movement is significant: Designed to dig as much as 16 feet (5 meters) underground to gauge the heat escaping from the planet's interior, the mole has only managed to partially bury itself since it started hammering in February 2018.

The clumpy and lumpy death of a star

In 1572, Danish astronomer Tycho Brahe was among those who noticed a new bright object in the constellation Cassiopeia. Adding fuel to the intellectual fire that Copernicus started, Tycho showed this "new star" was far beyond the Moon, and that it was possible for the Universe beyond the Sun and planets to change.

Spiral arms in a young accretion disk around a baby star

An international research team, led by Chin-Fei Lee at the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA, Taiwan), has detected a pair of spiral arms in an accretion disk around a protostar (baby star), using the Atacama Large Millimeter/submillimeter Array (ALMA). Interestingly, these spiral density enhancements make the disk appear like a "space whirlpool." The finding not only supports current theories of accretion disk feeding processes, but also potentially brings key insights into the[..]

Near-Earth asteroids spectroscopic survey at the Isaac Newton telescope

The study of near-Earth asteroids (NEAs) is driven by both scientific and practical reasons. Because of their proximity to our planet, they can provide key information regarding the delivery of water and organic-rich material to the early Earth, and the subsequent emergence of life. On the other hand, these small bodies of the Solar System have non-negligible long-term probabilities of colliding with the Earth, and can be targets of future space exploration.

Dark matter tugs the most massive spiral galaxies to breakneck speeds

When it comes to galaxies, how fast is fast? The Milky Way, an average spiral galaxy, spins at a speed of 130 miles per second (210 km/sec) in our Sun's neighborhood. New research has found that the most massive spiral galaxies spin faster than expected. These "super spirals," the largest of which weigh about 20 times more than our Milky Way, spin at a rate of up to 350 miles per second (570 km/sec).

A new theory to explain how the dunes on Titan formed

A trio of researchers with the University of Hawaii has developed a new theory to explain how the dunes on Saturn's largest moon, Titan, may have formed. In their paper published in the journal Science Advances, Matthew Abplanalp, Robert Frigge and Ralf Kaiser suggest that rather than forming from rainfall, the dunes have formed on the moon's surface.

Stormy cluster weather could unleash black hole power and explain lack of cosmic cooling

"Weather" in clusters of galaxies may explain a longstanding puzzle, according to a team of researchers at the University of Cambridge. The scientists used sophisticated simulations to show how powerful jets from supermassive black holes are disrupted by the motion of hot gas and galaxies, preventing gas from cooling, which could otherwise form stars. The team publish their work in the journal Monthly Notices of the Royal Astronomical Society.

SUPERB survey detects new slowly-spinning radio pulsar

Astronomers have detected a new slowly rotating radio pulsar as part of the SUrvey for Pulsars and Extragalactic Radio Bursts (SUPERB). The newly found object, designated PSR J2251−3711, turns out to be one of the slowest spinning radio pulsars known to date. The finding is detailed in a paper published October 9 on arXiv.org.
