Friday, January 25, 2019: During the total lunar eclipse on Monday (Jan. 21), the moon temporarily blocked our view of the star HIP 39749, located almost 6,000 light-years away in the Cancer constellation. In this animated timelapse, you can see the star emerging from the bottom of the moon after this stellar occultation. Astronomers at the European Space Astronomy Center in Spain recorded the event using an 8-inch (20-centimeter) reflector scope. — Hanneke Weitering

Aurora Spotted from Space


Thursday, January 24, 2019: A lime-green aurora glows above Earth's city lights in this view from the International Space Station. At the time this photo was taken, the space station was orbiting about 258 miles (415 kilometers) above Russia and the Ukraine. A portion of the space station's solar array is visible in the top left corner of the image. — Hanneke Weitering

Chile's Vibrant Night Sky

Wednesday, January 23, 2019: The Milky Way shimmers over Chile's Atacama Desert in this stunning view by astrophotographer Petr Horálek of the European Southern Observatory (ESO). The long line of yellow street lights marks the road between ESO's Paranal Observatory and the Residencia, a hotel that provides lodging for astronomers and other staff of the observatory. — Hanneke Weitering

Total Lunar Eclipse Over Chile

Tuesday, January 22, 2019: The Super Blood Wolf Moon peeks out from behind some foliage in this image taken by astrophotographer Yuri Beletsky in Santiago, Chile. Although the temperature in Chile was more bearable than it was for many eclipse photographers facing a cold front in the U.S., Beletsky said he struggled with thick cloud coverage throughout his shoot. He captured this lucky shot through a break in the clouds. — Hanneke Weitering

Martin Luther King, Jr. and the Supermoon

Monday, January 21, 2019: The first "supermoon" of 2019 arrived on the Martin Luther King Jr. holiday today, along with a "blood moon" lunar eclipse. In this photo, a previous supermoon sets behind the Martin Luther King Jr. Memorial in Washington on Nov. 14, 2016. That supermoon did not coincide with a lunar eclipse, but it was the closest encounter between Earth and the moon in more than 68 years. See AMAZING photos of the 2019 Blood Moon! — Hanneke Weitering

A Strangely Spherical Galaxy

Friday, January 18, 2019: The bright, fuzzy light in this deep-space image is a spherical collection of stars known as Messier 89. Although it's classified as an elliptical galaxy, Messier 89 appears to be almost perfectly spherical, which is highly unusual. However, astronomers suspect that Messier 89's peculiar shape could just be an illusion, or a product of both the galaxy's orientation and our point of view. — Hanneke Weitering

A Grapefruit in Space

Thursday, January 17, 2019: A fresh grapefruit floats in microgravity at the International Space Station in this photo taken by Canadian astronaut David Saint-Jacques. "Enjoying the last few fresh items until the next resupply spacecraft," Saint-Jacques tweeted yesterday from the orbiting laboratory. The next cargo shipment is scheduled to launch in March on a SpaceX Dragon spacecraft, so he and his Expedition 58 crewmates will have to wait a few weeks before more fresh fruit arrives. — Hanneke Weitering

The Triangulum Galaxy

Wednesday, January 16, 2019: Behold: the sharpest view of the Triangulum Galaxy ever! This composite image combines 54 frames captured by the Hubble Space Telescope's Advanced Camera for Surveys. Also known as Messier 33, the Triangulum Galaxy is located about 3 million light-years from Earth in the constellation of Triangulum. — Hanneke Weitering

Tuesday, January 15, 2019: Three big storms churn through Jupiter's turbulent atmosphere in this image from NASA's Juno spacecraft. Citizen scientist Kevin Gill processed the image using data the spacecraft collected during a close flyby of the planet on Dec. 21, 2018. — Hanneke Weitering

Monday, January 14, 2019: Stars and galaxies twinkle above Chile's Atacama Desert while a satellite flare zips across the night sky in this image by Petr Horálek, a photo ambassador for the European Southern Observatory. The empty landscape below has been selected to be the future site for part of the Cherenkov Telescope Array, an international project that will search the cosmos for gamma radiation using an array of 99 telescopes located in both the Southern Hemisphere and Northern Hemisphere. — Hanneke Weitering
