Eta Carinae is Getting Brighter Because a Dust Cloud was Blocking our View
A new study by an international team reveals that Eta Carinae will soon be so bright that we won’t be able to see its famous nebula anymore.
Oumuamua Could be the Debris Cloud of a Disintegrated Interstellar Comet
Since it was first detected hurling through our Solar System, the interstellar object known as ‘Oumuamua has been a source of immense scientific interest. Aside from being extrasolar in origin, the fact that it has managed to defy classification time and again has led to some pretty interesting theories
NASA used Curiosity’s Sensors to Measure the Gravity of a Mountain on Mars
Some very clever people have figured out how to use MSL Curiosity’s navigation sensors to measure the gravity of a Martian mountain.
Astronomers Process Hubble’s Deepest Image to get Even More Data, and Show that Some Galaxies are Twice as big as Previously Believed
It allowed us to spot auroras on Saturn and planets orbiting distant suns. It permitted astronomers to see galaxies in the early stages of formation, and look back to some of the earliest periods in the Universe.
Newborn Stars in the Orion Nebula Prevent Other Stars from Forming
The Orion Nebula is one of the most observed and photographed objects in the night sky. At a distance of 1350 light years away, it’s the closest active star-forming region to Earth.
Uh oh, a Recent Study Suggests that Dark Energy’s Strength is Increasing
Staring into the Darkness The expansion of our universe is accelerating. Every single day, the distances between galaxies grows ever greater. And what’s more, that expansion rate is getting faster and faster – that’s what it means to live in a universe with accelerated expansion
When Does the Sun Rise… Really?
It’s strange but true… we may not fully understand one of the simplest metrics in observational astronomy: just what time does the Sun rise… really

Crew Dragon Rolls Out to the Launch Pad. Demo-1 Flight Should Happen Shortly
The long-anticipated first flight of the SpaceX Crew Dragon is almost here. Early in January, the Crew Dragon was rolled out of its hangar at Kennedy Space Center, and on January 24th it performed a brief static firing as part of its testing
One of the Oldest Earth Rocks Turned up on the Moon, of all Places
A recent study has determined that the oldest sample of Earth rock ever discovered (~4 billion years old) was actually found on the Moon. The post One of the Oldest Earth Rocks Turned up on the Moon, of all Places appeared first on Universe Today
Carnival of Space #596
This week’s Carnival of Space is hosted by Allen Versfeld at his Urban Astronomer blog.
Tiny Object Found at the Edge of the Solar System for the First Time. A Kuiper Belt Object that’s Only 2.6 km Across
The Kuiper Belt, or the Edgeworth-Kuiper Belt, is home to ancient rocks. Kuiper Belt Objects, or KBOs, are remnants of the early planet-formation days of our Solar System. Small KBOs, in the 1 km.
Astronomers are Continuing to Watch the Shockwaves Expand from Supernova SN1987A, as they Crash Into the Surrounding Interstellar Medium
An international team of researchers was able to accurately measure the effect that a supernova shock wave had on the surrounding gas for the first time. The post Astronomers are Continuing to Watch the Shockwaves Expand from Supernova SN1987A, as they Crash Into the Surrounding Interstellar Medium appeared first on Universe Today
Without the Impact that Formed the Moon, We Might Not Have Life on Earth
The Earth wasn’t formed containing the necessary chemicals for life to begin. One well-supported theory, called the “late veneer theory”, suggests that the volatile chemicals needed for life arrived long after the Earth formed, brought here by meteorites. But a new study challenges the late veneer theory.
Here it is, the high resolution photo of MU69 We’ve all been waiting for.
A newly-processed image of Ultima Thule provides the highest-resolution picture of the object to date.
Quasars with a Double-Image Gravitational Lens Could Help Finally Figure out how Fast the Universe is Expanding
How fast is the Universe expanding?
What Would be the Benefits of an Interstellar Probe?
A new study from the Initiative for Interstellar Studies outlines the benefits and requirements of sending a probe on an interstellar mission.
A Planetary Nebula Like This Will Only be Visible for About 10,000 Years Before it Fades Away
For some stars, their last act is a final exhalation of gases, which we call a planetary nebula. While a living being’s last breath is closely followed by death, a star can continue to shine. And that shining illuminates the final exhalation of gases like a cosmic, diaphanous veil
