It’s been 124 days since the Parker Solar Probe was launched, and several weeks since it made the closest approach any spacecraft has ever made to a star.
According to a new analysis of Rosetta data, the orbiter passed through the bow shock of Comet 67/P several times during its mission. The post Rosetta Flew Through the Bow Shock of Comet 67P Several Times During its Mission appeared first on Universe Today
InSight has been on the Martian surface for almost three weeks, prepping itself for all the science it’s going to do. But in the meantime, it’s doing what any self-respecting, modern robotic lander does: Taking pictures of itself
You’re Looking at an Actual Image of a White Dwarf Feeding on Material from a Larger Red Giant, 650 Light Years from Earth.
The SPHERE planet-hunting instrument on the European Southern Observatory’s Very Large Telescope captured this image of a white dwarf feeding on its companion star, a type of Red Giant called a Mira variable.
In a recent study, an international team of scientists present their concept for a lightsail and spacecraft that could make the journey to the nearest star in about 100 years. The post Exactly How We Would Send our First Laser-Powered Probe to Alpha Centauri appeared first on Universe Today .
There’s a Surprising Amount of Life Deep Inside the Earth. Hundreds of Times More Mass than All of Humanity
Scientists with the Deep Carbon Observatory (DCO) are transforming our understanding of life deep inside the Earth, and maybe on other worlds. Their discoveries suggest that abundant life could exist in the sub-surface of other planets and moons, even where temperatures are extreme, and energy and nutrients are scarce. They’ve also discovered that all of … Continue reading “There’s a Surprising Amount of Life Deep Inside the Earth
The ESA’s NELIOTA project is busy monitoring the dark side of the Moon for impact flashes, which could tell us more about the risk of asteroids hitting Earth.
For many years, scientists have been studying how supernovae could affect life on Earth. Supernovae are extremely powerful events, and depending on how close they are to Earth, they could have consequences ranging from the cataclysmic to the inconsequential.
The Voyager 2 recently crossed the outer boundary of the heliosphere, where it joins the Voyager 1 spacecraft in interstellar space The post Finally! Voyager 2 is Now in Interstellar Space appeared first on Universe Today .
When it comes to meteor showers, the calendar year always seems to save the best for last. We’re referring to the Geminid meteor shower, one of the sure fire bets for dependable meteor showers. In fact, in recent years, the Geminids have been upstaging that other yearly favorite: the August Geminids
The InSight lander recently used two its instruments to record vibrations caused by Martian wind, effectively capturing what it sounds like on the surface of Mars.
NASA’s OSIRIS-REx (Origins, Spectral Interpretation, Resource Identification, Security-Regolith Explorer) has found water on the asteroid Bennu. Bennu is OSIRIS-REx’s only target, and though the spacecraft arrived at the asteroid on December 3rd, some of its instruments have been trained on the asteroid since mid-August. And two of those instruments detected water on Bennu

Everyone knows about the extinction of the dinosaurs. A cataclysmic asteroid strike about 66 million years ago (mya) caused the Death of the Dinosaurs.
A handful of spacecraft have used ion engines to reach their destinations, but none have been as powerful as the engines on the BepiColombo spacecraft. BepiColombo is a joint mission between the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA.) It was launched on October 20, 2018, and has gone through weeks … Continue reading “Mercury-Bound BepiColombo is About to Start Using the Most Powerful Ion Engines Ever Sent to Space” The post Mercury-Bound BepiColombo is About to Start Using the Most Powerful Ion Engines Ever Sent to Space appeared first on Universe Today .
Located in the northern hemisphere, between the two “dippers”, is the Draco constellation – one of the 48 compiled by Ptolemy and one of the 88 recognized by the IAU. The post The Draco Constellation appeared first on Universe Today .
Some new images sent home by the InSight Lander show the robotic arm and the craft’s instruments waiting on deck, on the surface of Mars.
Imagine yourself in a boat on a great ocean, the water stretching to the distant horizon, with the faintest hints of land just beyond that. It’s morning, just before dawn, and a dense fog has settled along the coast
The rate at which Greenland is losing its ice is accelerating. This unsurprising conclusion comes from a new study based on 25 years of satellite data from the European Space Agency
Most of us think of distant sites such as Death Valley, the Kalahari Desert or the Canary Islands when it comes to dark skies. And while it’s true that many observers are now traveling farther and farther away from home in search of truly dark skies, that trip need not be as far as you think
