Earlier this week, a Soyuz spacecraft launched to the International Space Station with three people on board. But only one of them was a cosmonaut. The other two crew members were Russian actress Yulia Peresild and film producer Klim Shipenko. They will be on the ISS for 12 days to film scenes for an upcoming movie, called “Challenge.”
Star Trek meets star reality as William Shatner, the iconic 90-year-old actor, will fly on the next Blue Origins suborbital launch on October 12th.
A supermassive black hole (SMBH) likely resides at the center of the Milky Way, and in the centers of other galaxies like it. It’s never been seen though. It was discovered by watching a cluster of stars near the galactic center, called S stars.
Even the most supermassive of the supermassive black holes aren’t very large, making it extremely difficult to measure their sizes. However, astronomers have recently developed a new technique that can estimate the mass of a black hole based on the movement of hot gas around them – even when the black hole itself it smaller than a single pixel.
Not all who wander are lost – but sometimes their cell phone reception is. That might change soon if a plan to project basic cell phone coverage to all parts of the globe comes to fruition. Lynk has already proven it can use a typical smartphone to bound a standard SMS text message off a low-earth-orbiting satellite, and they don’t plan to stop there.
The Mars Perseverance rover is on the move! The HiRISE camera on the Mars Reconnaissance Orbiter spotted the rover from above, the first view since shortly after the rover landed in February 2021. Perseverance appears as the white speck in the center of the image above, in the the “South Séítah” area of Mars’ Jezero Crater.
Carl Sagan once famously, and sarcastically, observed that, since we couldn’t see what was going on on the surface of Venus, there must be dinosaurs living there. Once humans started landing probes on the planet’s surface, any illusion of a lush tropical world was quickly dispelled. Venus was a hellscape of extraordinary temperatures and pressures that would make it utterly inhospitable to anything resembling Earth life.
You know the feeling …. seeing Jupiter through your own telescope. If it gives you the chills — like it does for me — then you’ll know how the team for the Lunar Reconnaissance Orbiter felt when they turned their spacecraft around – yes, the orbiter that’s been faithfully circling and looking down at the Moon since 2008 – and saw the giant planet Jupiter with their camera. If you zoom in on the picture, you can even see Jupiter’s Galilean moons.
You could say that the study of extrasolar planets is in a phase of transition of late. To date, 4,525 exoplanets have been confirmed in 3,357 systems, with another 7,761 candidates awaiting confirmation. As a result, exoplanet studies have been moving away from the discovery process and towards characterization, where follow-up observations of exoplanets are conducted to learn more about their atmospheres and environments.
Astronomers have been using gravitational waves to detect merging black holes for years now, but may have to rely on pulsars – rapidly spinning neutron stars – to observe the mergers of supermassive black holes.
Usually, when the topic of asteroid mining comes up, thoughts turn to the riches of the asteroid belt between Mars and Jupiter. The sheer size and scale of the available resources in these asteroids are astounding and overshadow a much more accessible resource – Near-Earth Asteroids (NEAs) that are much closer to home. Now a team from the University of Arizona (UA) has spent some time looking at these near neighbors and realized some are very similar to one of the most famous asteroids in the belt – Psyche.
Materials science has once again come through for space exploration. Researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO) have developed a coating that could increase the sensitivity of LIGO by almost an order of magnitude. That would increase the detection rate of the gravitational waves the observatory is seeking from about once a week to once a day, mainly due to the increased volume of space that the observatory’s interferometers would be able to collect signals from.
Welcome back to our Fermi Paradox series, where we take a look at possible resolutions to Enrico Fermi’s famous question, “Where Is Everybody?” Today, we examine the possibility that we haven’t heard from any aliens is because no one is transmitting!
As the planets of our Solar System demonstrate, understanding the solar dynamics of a system is a crucial aspect of determining habitability. Because of its protective magnetic field, Earth has maintained a fluffy atmosphere for billions of years, ensuring a stable climate for life to evolve. In contrast, other rocky planets that orbit our Sun are either airless, have super-dense (Venus), or have very thin atmospheres (Mars) due to their interactions with the Sun.
Remember when engineers proposed one-way trips to Mars, because round trips are just too expensive to bring people back to Earth again?
Now that we know that interstellar objects (ISOs) visit our Solar System, scientists are keen to understand them better. How could they be captured? If they’re captured, what happens to them? How many of them might be in our Solar System?
NASA has delayed their Artemis mission to the Moon, but that doesn’t mean a return to the Moon isn’t imminent. Space agencies around the world have their sights set on our rocky satellite. No matter who gets there, if they’re planning for a sustained presence on the Moon, they’ll require in-situ resources.
The search for planets beyond our Solar System has grown immensely during the past few decades. To date, 4,521 extrasolar planets have been confirmed in 3,353 systems, with an additional 7,761 candidates awaiting confirmation. With so many distant worlds available for study (and improved instruments and methods), the process of exoplanet studies has been slowly transitioning away from discovery towards characterization.
Scientists have begun studying the samples returned from the Moon by China’s Chang’e-5 mission in December 2020, and a group of researchers presented their first findings at the Europlanet Science Congress (EPSC) last week.
The Colorado Ultraviolet Transit Experiment (aptly nicknamed CUTE) is a new, NASA-funded mission that aims to study the atmospheres of massive, superheated exoplanets – known as hot Jupiters – around distant stars. The miniaturized satellite, built by the Laboratory for Atmospheric and Space Physics (LASP) at the University of Colorado Boulder, is set to launch this Monday, September 27th on an Atlas V rocket.
