Two “Super Mercury” Exoplanets Found in a Single System
There’s a star system out there with three super-Earth planets and two super-Mercuries. Super-Earths are fairly familiar types of exoplanets, but super-Mercuries are rare. Those are planets with the same composition as our own Mercury, but larger and denser. Yet, here’s HD 23472, showing off two of eight known super-Mercuries in the galaxy.
New evidence for liquid water on Mars suggests the planet is geothermally active
Martian ice caps dip and rise and it may be evidence of liquid water lurking underneath them But what keeps that water from freezing?
What are wormholes? An astrophysicist explains these shortcuts through space-time
A wormhole is like a tunnel between two distant points in our universe that cuts the travel time from one point to the other.
International Observe the Moon Night 2022: Don't miss these livestreams and events on Saturday (Oct. 1)
Celebrate "International Observe the Moon Night" 2022 on Saturday (Oct. 1) virtually with livestreams or in person at an event near you.
A Computer Algorithm is 88% Accurate in Finding Gravitational Lenses
Astronomers have been assessing a new machine learning algorithm to determine how reliable it is for finding gravitational lenses hidden in images from all sky surveys. This type of AI was used to find about 5,000 potential gravitational lenses, which needed to be confirmed. Using spectroscopy for confirmation, the international team has now determined the technique has a whopping 88% success rate, which means this new tool could be used to find thousands more of these magical quirks of physics.
Hurricane Ian regains strength, heads toward South Carolina as NASA's Florida spaceport recovers
Hurricane Ian regained strength as it barreled toward South Carolina on Friday (Sept. 30) after passing over NASA's Kennedy Space center spaceport in Florida a day earlier.
US Space Force gets its 2nd-ever chief
On Thursday (Sept. 29), the Senate unanimously confirmed Lt. Gen. B. Chance Saltzman as chief of space operations for the Space Force.
Hubble Space Telescope spots protective shield against greedy Milky Way
An odd shield of supercharged gas protects dwarf galaxies from being ripped apart by the gravitational pull of the Milky Way, 30 years' worth of observations by the Hubble Space Telescope reveal.
World Space Week centers space sustainability for this year's events
In the 65 years since humanity's first satellite, the number of those in orbit is causing issues for astronomy and space security.
Advanced AI discovers a treasure trove of gravitational lenses
A machine-learning algorithm has helped astronomers discover thousands of gravitational lenses predicted by Einstein.
A Single High-Resolution Image of Dimorphos Stacked From DART’s Final Images
Here’s a sharper view of Dimorphos, the small asteroid moonlet that the DART (Double Asteroid Redirection Test) spacecraft intentionally crashed into. Eydeet on Imgur created a higher resolution image of Dimorphos by stacking the last few images received from the spacecraft before impact.
Europe’s space industry gathers at ESA
ESA welcomed a record 1700 visitors from 800 companies and institutions to its Industry Space Days event on 28–29 September at ESTEC, its technical centre in The Netherlands. It is a place where industry can meet and share their ideas for new emerging uses of space and commercial potential.
Celestron Astro Fi 102 telescope review
Its reasonable price, motorized functionality and SkyPortal app make this a good telescope for beginners.
Earth From Another Sun space MMO is an amazing homage to Starfield and Halo
Earth From Another Sun offers a Starfield- and Halo-inspired approach to a space-based, first-person shooter.
A Dwarf Galaxy Passed Close to the Milky Way and Left Ripples in its Wake
When you imagine the collision of galaxies, you probably think of something violent and transformational. Spiral arms ripped apart, stars colliding, cats and dogs living together, mass hysteria. The reality is much less dramatic. As a recent study shows, our galaxy is in a collision right now.
Why are sunspots black?
Why are sunspots black? According to astronomers, it may be a big, cosmic optical illusion.
Stars Spiral Inward to the Cores of Stellar Nurseries
Astronomers studying a stellar cluster within the Small Magellanic Cloud (SMC) have found young stars spiraling in towards the center of the cluster. The cluster, NGC 346, is an open cluster embedded within a glowing cloud of gas, which is typical of stellar nurseries – places where new stars are formed. The outer spiral arm of this star forming region appears to be funneling gas, dust and new stars into the center, which researchers describe as an efficient way to fuel the birth of new stars.
3D sky: How astronomers measure the size, luminosity and distance of stars
Stars differ in size, luminosity and distance from us. We discuss how astronomers measure these three values to understand the three-dimensional sky.
See the crescent moon shine above the red star Antares tonight (Sept. 30)
