Does the Milky Way have too many satellite galaxies?
The Large and Small Magellanic Clouds are well-known satellite galaxies of the Milky Way, but there are more. It is surrounded by at least 61 within 1.4 million light years (for context the Andromeda galaxy is 2.5 million light years away) but there.....»»

New research challenges dark matter theory in galaxy formation
The standard model for how galaxies formed in the early universe predicted that the James Webb Space Telescope (JWST) would see dim signals from small, primitive galaxies. But data are not confirming the popular hypothesis that invisible dark matter.....»»
Satellite data analysis shows wildland-urban interface areas have grown by 35% over past two decades
A trio of environmental scientists at the Chinese Academy of Sciences, Institute of Geographic Sciences and Natural Resources Research, working with a colleague from China's Ministry of Education, has found evidence via satellite analysis that global.....»»
Star"s disappearance in Andromeda marks the birth of a black hole
Massive stars about eight times more massive than the sun explode as supernovae at the end of their lives. The explosions, which leave behind a black hole or a neutron star, are so energetic they can outshine their host galaxies for months. However,.....»»
Powerful new US-Indian satellite will track Earth"s changing surface
Data from NISAR will improve our understanding of such phenomena as earthquakes, volcanoes, and landslides, as well as damage to infrastructure......»»
How to build a home radio telescope to detect clouds of hydrogen in the Milky Way
If I ask you to picture a radio telescope, you probably imagine a large dish pointing to the sky, or even an array of dish antennas such as the Very Large Array. What you likely don't imagine is something that resembles a TV dish in your neighbor's b.....»»
Rocket Report: Australia says yes to the launch; Russia delivers for Iran
The world's first wooden satellite arrived at the International Space Station this week. Welcome to Edition 7.19 of the Rocket Report! Okay, we get it. We received more submission.....»»
Mighty radio bursts linked to massive galaxies: New clues about how magnetars form
Since their discovery in 2007, fast radio bursts—extremely energetic pulses of radio-frequency light—have lit up the sky repeatedly, leading astronomers on a chase to uncover their origins. Currently, confirmed fast radio bursts, or FRBs, number.....»»
World’s first wooden satellite launched to space
The tiny wooden cubesat arrived at the International Space Station aboard a SpaceX Dragon ship and will be deployed to orbit before the end of this year......»»
NRO chief: “You can’t hide” from our new swarm of SpaceX-built spy satellites
"A satellite is always coming over an area within a given reasonable amount of time." The director of the National Reconnaissance Office has a message for US adversaries around th.....»»
World"s first wooden satellite launched into space
The world's first wooden satellite has blasted off on a SpaceX rocket, its Japanese developers said Tuesday, part of a resupply mission to the International Space Station......»»
Webb confirms a longstanding galaxy model
Perhaps the greatest tool astronomers have is the ability to look backward in time. Since starlight takes time to reach us, astronomers can observe the history of the cosmos by capturing the light of distant galaxies......»»
Oh buoy! A new-generation satellite mission to study color of the ocean from space
Curtin University has joined forces with NASA, University of Miami, San José State University and the National Institute of Standards and Technology on a new-generation satellite mission to study the color of the ocean from space, providing vital in.....»»
Observations detect hundreds of possible supergiant stars in two nearby galaxies
Using the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), Chinese astronomers have identified nearly 300 candidate supergiant stars in the Andromeda and Triangulum galaxies. The finding was reported in a research paper published O.....»»
