SpaceX has completed its 21st Falcon 9 launch of 2022, continuing an impressive average cadence of more than one launch per week. After an unexplained 40-minute delay from 6:20 am EDT, former Falcon Heavy booster B1052 lifted off from Kennedy Space Center Launch Complex 39A shortly after sunrise at 6:59 am EDT (10:59 UTC) on … Read more
Like many octopuses, the California two-spot octopus (Octopus bimaculoides) declines and dies shortly after breeding. Credit: Tom Kleindinst, Marine Biological Laboratory Changes in cholesterol production lead to a tragic octopus death spiral. New research finds remarkable parallels in steroid hormone biology across cephalopods, mice, and humans that can have dire consequences when disrupted. Despite their … Read more
The team will continue to monitor the signal closely as they continue to determine whether the invalid data is coming directly from the AACS or another system involved in producing and sending telemetry data. Until the nature of the issue is better understood, the team cannot anticipate whether this might affect how long the spacecraft … Read more
According to the researchers, the process is still harnessing the power of the Sun, whose radiative output warms up the Earth during the day. At night, this energy is radiated back out into the cold voice of outer space in the form of infrared light — the same thing that allows wearers of night-vision goggles … Read more
Cutting edge instruments and perfect cosmic alignments have allowed astronomers to peer into the nursery rooms of some of the oldest galaxies in the universe. A new paper published Thursday in the journal Nature describes how scientists used a technique called gravitational lensing and new spectrograph technology to view and characterize massive clouds of gas … Read more
A drastic change in steroid hormone levels in female octopuses after they lay eggs causes them to mutilate themselves to death, a new study has revealed. Cephalopods, a group that includes octopuses and squids, have the largest central nervous systems and the greatest brain-to-body mass ratios among spineless creatures. However, cephalopods are unusually short-lived, unlike … Read more
Side view of the Moltke crater taken from Apollo 10. Credit: Public Domain Billions of years ago, a series of volcanic eruptions broke loose on the moon, blanketing millions of thousands of square miles of the orb’s surface in hot lava. Over the eons, that lava created the dark blotches, or maria, that gives the … Read more
Many animal species die after they reproduce. But in octopus mothers, this decline is particularly alarming: In most species, as an octopus mother’s eggs get close to hatching, she stops eating. She then leaves her protective huddle over her brood and becomes bent on self-destruction. She might beat herself against a rock, tear at her … Read more
This is the first image of Sagittarius A* (Sgr A*), the supermassive black hole at the center of our galaxy, captured by the Event Horizon Telescope (EHT). It is the first direct visual evidence of the presence of this black hole. Credit: EHT Collaboration Astronomers reveal the first image of the[{” attribute=””>black hole at the … Read more
The Martian InSight lander will no longer be able to function within months as dust continues to pile up on its solar panels, starving it of energy, NASA reported on Tuesday. Launched from Earth in 2018, the six-metre-wide machine’s mission was sent to study the Red Planet below its surface. InSight is armed with a … Read more
