This month's astronomy podcast guides you around the nighttime sky during April, giving you easy-to-follow help for finding bright planets and key stars after the Sun goes down.
Astronomers have found a peculiar object: a fluffy galaxy that has little to no dark matter.
NASA officials announced Wednesday that the James Webb Space Telescope launch would be delayed until approximately May 2020. But before the mission can launch, its managers may have to face Congress.
A new analysis of more than 800 telescopic observations suggests that our first known interstellar visitor could have the shape of a cigar or a fat disk.

China's premier space station, Tiangong 1, has a one-way ticket into the Earth's atmosphere later this month. See it before it's no more.
New ALMA observations reveal a fiber-like structures within a longer, well-studied filament. These fibers contain the seeds of future stars.
A controversial 1950 book by Immanuel Velikovsky declared that our neighbor world was spawned by Jupiter 3,500 years ago and nearly struck Earth — twice.
A physicist has incorporated a quantum mechanical idea with general relativity to arrive at a new alternative to black hole singularities.
The University of Chicago is ending its support for Yerkes Observatory, a historic, castle-like building built to house a gigantic telescope, on October 1st. Its future remains unclear.
Hubble reveals a relic galaxy, Dawn sees the surface of asteroid Ceres changing, and scientists probe an auroral phenomenon named "Steve."
Stephen Hawking, renowned physicist, famed science communicator, and all-around inspiration, has passed away at the age of 76.
Hubble's powerful eye scouts the outer planets once an Earth year, shedding light on planetary weather, like Jupiter's Great Red Spot and Neptune's Great Dark Spot.
Planet interactions are thought to be common as solar systems are first forming and settling down. A new study suggests that these close encounters could have a significant impact on the moons of giant exoplanets — and they may generate a large population of free-floating exomoons.
Got any plans in 46 million years? If not, you should keep an eye out for PSR J1946+2052 around that time — this upcoming merger of two neutron stars promises to be an exciting show!
NASA’s Juno spacecraft has found breathtaking cyclones at Jupiter’s poles and probed how deep the planet’s jet streams go.
A series of 11 sounding rocket flights from two remote locations in the Arctic circle will help unlock the secrets of the processes behind the Northern Lights.
A long-ago encounter between our galaxy and an orbiting dwarf might have ejected some of the Milky Way’s stars.
A non-partisan government office has issued a report warning of additional delays for the James Webb Space Telescope, which could pit the mission against its funding cap.
