Indonesia aims to increase broadband internet access across its country through the launch of its latest communications satellite aboard a SpaceX Falcon 9 rocket. The Telkomsat HTS 113BT satellite, also referred to as Merah Putih 2, is set to launch from Cape Canaveral Space Force Station at 3:11 p.m. EST (2011 UTC).
SpaceX launched the Merah Putih 2 satellite for Indonesian communications company Telkomsat today (Feb. 20).
A new solution to Einstein's theory of general relativity suggests a hypothetical star could be made of stacked black holes.
A new view from the European Southern Observatory's Very Large Telescope captures the abundant star-forming region at the center of the Milky Way.
A renovated Chinese underground lab has expanded the search for dark matter, offering new promise for the detection of this abundant yet elusive substance.
The Australian Space Agency is building a moon rover called "Roo-ver," slated to launch as early as 2026.
A new camera on the South Pole Telescope has used the Cosmic Microwave Background as a celestial treasure map that could lead to the secrets of dark matter.
Japan successfully tested its new flagship H3 rocket after an earlier version failed last year. The rocket lifted off from the Tanegashima Space Center on Saturday, February 17, reaching an orbital altitude of about 670 kilometers (420 miles). It deployed a set of micro-satellites and a dummy satellite designed to simulate a realistic payload.
Observations of galactic clusters made by the eROSITA X-ray all-sky survey could help solve a troubling tension in cosmology surrounding the 'lumpiness' of matter in the universe.
Astronomers have discovered a remarkable binary system in which a dead white dwarf star orbits a tiny stellar companion 72 times in 24 hours. The observation could help explain how tiny stars are born.
One of the central predictions of general relativity is that in the end, gravity wins. Stars will fuse hydrogen into new elements to fight gravity and can oppose it for a time. Electrons and neutrons exert pressure to counter gravity, but their stability against that constant pull limits the amount of mass a white dwarf or neutron star can have. All of this can be countered by gathering more mass together. Beyond about 3 solar masses, give or take, gravity will overpower all other forces and collapse the mass into a black hole.
One of the largest reentries in recent years, ESA’s ERS-2 satellite is coming down this week.

Astronomers have discovered a quasar that remained hidden for over the years is the brightest ever, powered by the fastest growing black hole ever discovered that eats a sun every day.

In Spring 2024, NASA will launch two tiny twin satellites as part of the PREFIRE mission that will journey to the poles to collect data that will help monitor climate change.
Varda Space Industries' first off-Earth manufacturing effort, a mission called W-1, is scheduled to land in northern Utah on Wednesday (Feb. 21).
The solar cycle has been reasonably well understood since 1843 when Samuel Schwabe spent 17 years observing the variation of sunspots. Since then, we have regularly observed the ebb and flow of the sunspots cycle every 11 years. More recently ESA’s Solar Orbiter has taken regular images of the Sun to track the progress as we head towards the peak of the current solar cycle. Two recently released images from February 2021 and October 2023 show how things are really picking up as we head toward solar maximum.
Non-Earth imaging company HEO Robotics captured breathtaking images of ESA's ERS-2 satellite as it tumbles towards an atmospheric reentry on Feb. 21.
Quasars are fascinating objects; supermassive black holes that are actively feasting on material from their accretion disks. The result is a jet that can outshine the combined light from the entire galaxy! There are smaller blackholes too that are the result of the death of stars and these also sometimes seem to host accretion disks and jets just like their larger cousins. We call these microquasars and, whilst there are similarities between them, there are differences too.
