The European Space Agency gave the green light to two missions on Thursday, one to detect ripples in spacetime called gravitational waves and another to probe the secrets of Earth's closest neighbouring planet Venus. The Laser Interferometer Space Antenna (LISA) will become the first mission to study gravitational waves from space, with a planned 2035 launch on an Ariane 6 rocket, the ESA sa

NASA's Ingenuity Mars helicopter, which made history by achieving the first powered flight on another world, has officially ended its nearly three-year mission after sustaining rotor damage during its last outing, the space agency said Thursday. The tissue-box sized aircraft, which hitched a ride to the Red Planet under the belly of the Perseverance rover, first lifted off the surface on A

ESA’s next mission to Venus was officially ‘adopted’ today by the Agency’s Science Programme Committee. EnVision will study Venus from its inner core to its outer atmosphere, giving important new insight into the planet's history, geological activity and climate.

Today, ESA’s Science Programme Committee approved the Laser Interferometer Space Antenna (LISA) mission, the first scientific endeavour to detect and study gravitational waves from space.

In November 2023, the A23a mega iceberg set sail after being grounded on the ocean floor for well over 40 years. Now, driven by winds and currents, A23a is heading away from Antarctic waters as seen in this new animation.

The iceberg calved from West Antarctica in 1986 but quickly grounded itself in the Weddell Sea where it remained for over four decades. At around 4000 sq km in area, more than four times the size of New York City, and just over 280 m thick, the berg currently holds the title for world’s largest iceberg.

Astronomers using the NASA/ESA Hubble Space Telescope observed the smallest exoplanet where water vapour has been detected in its atmosphere. At only approximately twice Earth’s diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy.

Earth planning date: Monday, January 22, 2024: Here in Toronto (along with much of Canada and the United States), we've spent the last few weeks bathed in an icy blast of arctic air, which has been quite a dramatic contrast with the very mild winter that we've had up until now. However, it is starting to warm back up, not just here but on Mars as well. We're just past the halfway point of the cu

Researchers from Shandong University of Science and Technology have published a study that sheds new light on the intricate nature of tropospheric delays impacting Global Navigation Satellite Systems (GNSS). This study, featured in the journal Satellite Navigation, goes beyond the traditional isotropic and anisotropic assumptions in tropospheric modeling, introducing a novel perspective on the n
