Smallest star ever observed is part of an exotic binary system

Phase-folded RV curve and double-band light curves for J0526. Top, RV curve derived from Keck/LRIS and GTC/OSIRIS observations. The dotted-dashed line is the best-fitting sinusoidal model. Middle and bottom, g- and r-band phase-folded light curves provided by LJT and ZTF. The purple solid lines represent the best-fitting light-curve models obtained from the ellc package. The […]

Impending European satellite reentry highlights debris mitigation challenges

WASHINGTON — The impending reentry of a defunct European satellite serves as a reminder of the hazards posed by existing objects even as agencies work to mitigate the growth of orbital debris. The European Space Agency’s European Remote Sensing (ERS) 2 satellite is expected to reenter on Feb. 21 after nearly two decades in orbit. […]

These supernovas are whipping up a storm, contributing to cosmic life and death

Astronomers have discovered a hitherto unknown source of the cosmic dust. As to why this dust is important to track? Well, these particles basically act as building blocks for stars. The international team found that such dust can be created by a type of cosmic explosion that occurs when a dead white dwarf star strips […]

Rocket Lab Electron rocket lifts off with space debris removal mission – Spaceflight Now

A small satellite that will inspect a discarded rocket body in orbit lifted off Sunday/Monday on a mission to develop techniques for removing space debris. The satellite built by Japan-based Astroscale […]

Look at How Much the Sun Has Changed in Just Two Years

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 […]

ESA – Tobago oil spill

Before and after satellite images from the Copernicus Sentinel-1 mission show the scale of the oil spill that occurred off the shores of Trinidad and Tobago’s coastline earlier this week. The ship, identified as The Gulfstream, ran aground and overturned off the southern shores of Tobago Island. The final image of the animation, captured on […]

Tan This image from the NASA/ESA Hubble Space Telescope is teeming with color and activity. It features a relatively close star-forming region known as IRAS 16562-3959, which lies within the […]

India launches INSAT-3DS meteorological satellite with GSLV rocket

HELSINKI — India successfully launched a new generation meteorological satellite early Saturday. The 51.7-meter-long, three-stage Geosynchronous Satellite Launch Vehicle (GSLV) lifted off at 7:05 a.m. Eastern Feb. 17 (1205 UTC; 5:35 p.m. local) from the Satish Dhawan Space Centre. The INSAT-3DS meteorological satellite separated from the launcher around 19 minutes later. The satellite entered geosynchronous […]

Japan’s new H3 rocket reaches orbit for 1st time (video)

The second time was the charm for Japan’s new H3 rocket. The H3 reached orbit and successfully deployed a satellite this evening (Feb. 16), rebounding from a failure on its debut flight last year and getting back on track to becoming Japan’s workhorse rocket of the future. “I was so moved!” a commentator said during […]
