The InSight lander has been on Mars for 213 Sols on its mission to understand the interior of the red planet. It’s armed with a seismometer, a temperature and wind sensor, and other instruments. But it’s primary instrument, arguably, is the Mole, or the Heat Flow and Physical Properties Package (HP3.) And the Mole has been stuck for a while now.Continue reading “NASA’s Still Trying to Get InSight’s Mole Working Again. Progress is Slow.”
Out there in space is an unusual exoplanet name Gliese 3470 b (GJ 3470 b.) It’s a strange world, kind of like a hybrid between Earth and Neptune. It has a rocky core like Earth, but is surrounded by an atmosphere made of hydrogen and helium. That combination is unlike anything in our own Solar System.Continue reading “NASA Telescopes Reveal the Atmosphere of A Strange Hybrid Exoplanet”
7500 light years away is an object that (almost) needs no introduction: Eta Carinae. If you haven’t heard of it you should be following Universe Today more. Eta Carinae is a well-known and often-studied object in astronomy, partly because it’s prone to the kind of violent outbursts that really grab your attention.Continue reading “Hubble has a Brand New Picture of the Massive Star Eta Carinae. It Could Detonate as a Supernova Any Day Now”
On July 20th, 2019, exactly 50 years will have passed since human beings first set foot on the Moon. To mark this anniversary, NASA will be hosting a number of events and exhibits and people from all around the world will be united in celebration and remembrance. Given that crewed lunar missions are scheduled to take place again soon, this anniversary also serves as a time to reflect on the lessons learned from the last “Moonshot”.
For one, the Moon Landing was the result of years of government-directed research and development that led to what is arguably the greatest achievement in human history. This achievement and the lessons it taught were underscored in a recent essay by two Harva
Back in May 23rd, 2019, SpaceX launched the first batch of its Starlink constellation, a fleet of satellites that will fulfill Elon Musk’s promise to provide broadband satellite-internet access to the entire planet. The deployment of these sixty satellites was the first in a series of six planned launches that would see around 720 satellites orbiting at an operational altitude of 550 km (340 mi).
Over the course of the past month, SpaceX announced that all sixty of the satellites were responsive, but recently indicated that contact had been lost with three of them. According to a statement issued by a company spokesperson on June 28th, these three satellites pose no danger as they will deorbit “passively” and burn up in the atmosphere.Continue reading “SpaceX has Lost Contact With 3 of its Starlink Satellites”
To the scientifically uninitiated, it might seem like a frivolous idea: That those slight, wispy clouds that trail behind jet aircraft at such high altitudes could contribute to climate change. But they do.
Scientists love to measure things, and when they measured these contrails, which is short for condensation trails, they found bad news. Though they look kind of beautiful and ephemeral on a summer day, they pack an oversize punch when it comes to their warming effect.Continue reading “Airplane Contrails are Contributing to Global Warming Too”
Editor’s note: “Eight Years to the Moon: The History of the Apollo Missions” is a new book, just out today, written by Universe Today’s Nancy Atkinson, with a foreword by Apollo 9 astronaut Rusty Schweickart. The book tells the unique personal stories of over 60 engineers and scientists who worked behind the scenes to make the Apollo program
It has been said that within the next quarter century, the world’s first trillionaires will emerge. It is also predicted that much of their wealth will stem from asteroid mining, a burgeoning space industry where minerals and volatile compounds will be harvested from Near-Earth Asteroids. This industry promises to flood the market with ample supplies of precious metals like gold, silver
Beyond Earth, there’s the long-term prospect of the Main Asteroid Belt, which would provide even greater abundance. This is one of the reasons why NASA’s Psyche mission to explore the metal asteroid of the same name in the Main Belt has many people excited. While the exploration of this body
Relativity is used in more day to day situations than you may realize. In this episode, we will count (some of) the ways. This episode is brought to you live from the All-Stars Star Party in Indian Wells, California.
